Make role descriptors optional when creating API keys (#43481) (#43614)
This commit changes the `role_descriptors` field from required
to optional when creating API key. The default behavior in .NET ES
client is to omit properties with `null` value requiring additional
workarounds. The behavior for the API does not change.
Field names (`id`, `name`) in the invalidate api keys API documentation have been
corrected where they were wrong.

Closes #42053

Add kerberos grant_type to get token in exchange for Kerberos ticket (#42847) (#43355)
Kibana wants to create access_token/refresh_token pair using Token
management APIs in exchange for kerberos tickets. `client_credentials`
grant_type requires every user to have `cluster:admin/xpack/security/token/create`
cluster privilege.

This commit introduces `_kerberos` grant_type for generating `access_token`
and `refresh_token` in exchange for a valid base64 encoded kerberos ticket.
In addition, `kibana_user` role now has cluster privilege to create tokens.
This allows Kibana to create access_token/refresh_token pair in exchange for
kerberos tickets.

Note:
The lifetime from the kerberos ticket is not used in ES and so even after it expires
the access_token/refresh_token pair will be valid. Care must be taken to invalidate
such tokens using token management APIs if required.

Closes #41943

[Backport 7.x] OpenID Connect realm guide (#42836)
This commit adds a configuration guide for the newly introduced
OpenID Connect realm. The guide is similar to the style of the
SAML Guide and shares certain parts where applicable (role mapping)
It also contains a short section on how the realm can be used for
authenticating users without Kibana.

Albert Zaharovits fe5789ada1 Fix Has Privilege API check on restricted indices (#41226)
The Has Privileges API allows to tap into the authorization process, to validate
privileges without actually running the operations to be authorized. This commit
fixes a bug, in which the Has Privilege API returned spurious results when checking
for index privileges over restricted indices (currently .security, .security-6,
.security-7). The actual authorization process is not affected by the bug.

Support mustache templates in role mappings (#40571)
This adds a new `role_templates` field to role mappings that is an
alternative to the existing roles field.

These templates are evaluated at runtime to determine which roles should be
granted to a user.
For example, it is possible to specify:

    "role_templates": [
      { "template":{ "source": "_user_{{username}}" } }
    ]

which would mean that every user is assigned to their own role based on
their username.

You may not specify both roles and role_templates in the same role
mapping.

This commit adds support for templates to the role mapping API, the role
mapping engine, the Java high level rest client, and Elasticsearch
documentation.

Due to the lack of caching in our role mapping store, it is currently
inefficient to use a large number of templated role mappings. This will be
addressed in a future change.

Add support for API keys to access Elasticsearch (#38291)
X-Pack security supports built-in authentication service
`token-service` that allows access tokens to be used to 
access Elasticsearch without using Basic authentication.
The tokens are generated by `token-service` based on
OAuth2 spec. The access token is a short-lived token
(defaults to 20m) and refresh token with a lifetime of 24 hours,
making them unsuitable for long-lived or recurring tasks where
the system might go offline thereby failing refresh of tokens.

This commit introduces a built-in authentication service
`api-key-service` that adds support for long-lived tokens aka API
keys to access Elasticsearch. The `api-key-service` is consulted
after `token-service` in the authentication chain. By default,
if TLS is enabled then `api-key-service` is also enabled.
The service can be disabled using the configuration setting.

The API keys:-
- by default do not have an expiration but expiration can be
  configured where the API keys need to be expired after a
  certain amount of time.
- when generated will keep authentication information of the user that
   generated them.
- can be defined with a role describing the privileges for accessing
   Elasticsearch and will be limited by the role of the user that
   generated them
- can be invalidated via invalidation API
- information can be retrieved via a get API
- that have been expired or invalidated will be retained for 1 week
  before being deleted. The expired API keys remover task handles this.

Following are the API key management APIs:-
1. Create API Key - `PUT/POST /_security/api_key`
2. Get API key(s) - `GET /_security/api_key`
3. Invalidate API Key(s) `DELETE /_security/api_key`

The API keys can be used to access Elasticsearch using `Authorization`
header, where the auth scheme is `ApiKey` and the credentials, is the 
base64 encoding of API key Id and API key separated by a colon.
Example:-
```
curl -H "Authorization: ApiKey YXBpLWtleS1pZDphcGkta2V5" http://localhost:9200/_cluster/health
```

Permission for restricted indices (#37577)
This grants the capability to grant privileges over certain restricted
indices (.security and .security-6 at the moment).
It also removes the special status of the superuser role.

IndicesPermission.Group is extended by adding the `allow_restricted_indices`
boolean flag. By default the flag is false. When it is toggled, you acknowledge
that the indices under the scope of the permission group can cover the
restricted indices as well. Otherwise, by default, restricted indices are ignored
when granting privileges, thus rendering them hidden for authorization purposes.
This effectively adds a confirmation "check-box" for roles that might grant
privileges to restricted indices.

The "special status" of the superuser role has been removed and coded as
any other role:
```
new RoleDescriptor("superuser",
    new String[] { "all" },
    new RoleDescriptor.IndicesPrivileges[] {
        RoleDescriptor.IndicesPrivileges.builder()
            .indices("*")
            .privileges("all")
            .allowRestrictedIndices(true)
// this ----^
            .build() },
            new RoleDescriptor.ApplicationResourcePrivileges[] {
                RoleDescriptor.ApplicationResourcePrivileges.builder()
                    .application("*")
                    .privileges("*")
                    .resources("*")
                    .build()
            },
            null, new String[] { "*" },
    MetadataUtils.DEFAULT_RESERVED_METADATA,
    Collections.emptyMap());
```
In the context of the Backup .security work, this allows the creation of a
"curator role" that would permit listing (get settings) for all indices
(including the restricted ones). That way the curator role would be able to 
ist and snapshot all indices, but not read or restore any of them.

Security: remove SSL settings fallback (#36846)
This commit removes the fallback for SSL settings. While this may be
seen as a non user friendly change, the intention behind this change
is to simplify the reasoning needed to understand what is actually
being used for a given SSL configuration. Each configuration now needs
to be explicitly specified as there is no global configuration or
fallback to some other configuration.

DOCS: Add password_hash & refresh to Put User API (#35574)
PR #35242 formalised support for the password_hash field in the body
of the Put User security API.
Since this field is now validated and tested, it can also be
documented.

The Put User API also supports a "refresh" query parameter that was
not documented. This commit adds it to the docs.

Support PKCS#11 tokens as keystores and truststores (#34063)
This enables Elasticsearch to use the JVM-wide configured
PKCS#11 token as a keystore or a truststore for its TLS configuration.
The JVM is assumed to be configured accordingly with the appropriate
Security Provider implementation that supports PKCS#11 tokens.
For the PKCS#11 token to be used as a keystore or a truststore for an
SSLConfiguration, the .keystore.type or .truststore.type must be
explicitly set to pkcs11 in the configuration.
The fact that the PKCS#11 token configuration is JVM wide implies that
there is only one available keystore and truststore that can be used by TLS
configurations in Elasticsearch.
The PIN for the PKCS#11 token can be set as a truststore parameter in
Elasticsearch or as a JVM parameter ( -Djavax.net.ssl.trustStorePassword).

The basic goal of enabling PKCS#11 token support is to allow PKCS#11-NSS in
FIPS mode to be used as a FIPS 140-2 enabled Security Provider.

Security: remove wrapping in put user response (#33512)
This change removes the wrapping of the created field in the put user
response. The created field was added as a top level field in #32332,
while also still being wrapped within the `user` object of the
response. Since the value is available in both formats in 6.x, we can
remove the wrapped version for 7.0.

HLRest: add put user API (#32332)
This commit adds a security client to the high level rest client, which
includes an implementation for the put user api. As part of these
changes, a new request and response class have been added that are
specific to the high level rest client. One change here is that the response
was previously wrapped inside a user object. The plan is to remove this
wrapping and this PR adds an unwrapped response outside of the user
object so we can remove the user object later on.

Token API supports the client_credentials grant (#33106)
This change adds support for the client credentials grant type to the
token api. The client credentials grant allows for a client to
authenticate with the authorization server and obtain a token to access
as itself. Per RFC 6749, a refresh token should not be included with
the access token and as such a refresh token is not issued when the
client credentials grant is used.

The addition of the client credentials grant will allow users
authenticated with mechanisms such as kerberos or PKI to obtain a token
that can be used for subsequent access.

Tim Vernum 387c3c7f1d Introduce Application Privileges with support for Kibana RBAC (#32309)
This commit introduces "Application Privileges" to the X-Pack security
model.

Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.

Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.

Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
  objects
- a new "global" element on role definition to provide cluster object
  level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
  `kibana_system` roles to use and manage application privileges
