David Roberts a386b5727e [ML] Increase tokenization flexibility for categorization (elastic/x-pack-elasticsearch#3372)
By moving tokenization for categorization to Java we give users access to considerably more options for tokenizing their log messages prior to using ML to categorize them. Now all Elasticsearch analyzer functionality is available, which opens up the possibility to sensibly categorize non-English log messages.

Chris Earle e74f90eba0 [Monitoring] Add Cluster Alert for Nodes Changed (elastic/x-pack-elasticsearch#3504)
This creates a cluster alert that triggers whenever a node is:

- Added
- Removed
- Restarted (aka Removed and Added between collections)

Unlike all previous cluster alerts, this cluster is always instantly resolved because there is no way to otherwise resolve it later (especially if nodes are replaced).

This will require a small change to the UI so that it does not simply ignore resolved alerts.

Michael Basnight 220aa734ee Migrate actions to plugin core (elastic/x-pack-elasticsearch#3424)
This commit hacks up the xpack repo in such a way that it moves all
actions that the transport client uses to plugin core. It also moves
any classes that those actions use to plugin core, with a few
exceptions. I tried to split up any classes that pulled in server side
logic into the client, but that was not always 100% possible. Consider
this commit a guide, and since I do not know the codebase for each
plugin, consider it a best guess for what should be moved. A few other
things were merged in below.

This commit extracts the parts of Condition and AlwaysCondition that are
needed by classes that will be moved into the client package. The only
odd thing here is that since there are two parent classes (Condition and
AlwaysCondition) it was not possible to make AlwaysConditionInteral
extend from AlwaysCondition and still parse a ConditionInternal object,
which is what the ConditionFactory expects.

This commit removes the use of internal users in the User class, and
instead moves them to Authentication, where they are used.

jaymode f1f1be3927 Test: tests that use security index should not delete template
Tests that rely on the security index and security index template being present should not remove
the template between tests as this can cause test failures. The template upgrade service relies
on cluster state updates to trigger the template being added after a delete, but there is a
scenario where the test will just wait for template that never shows up as there is no cluster
state update in that time. Instead of fighting ourselves, we should just leave the template in
place.

Nik Everett 236f64a70e SQL: Fix SSL for JDBC and CLI for real this time (elastic/x-pack-elasticsearch#3277)
Previously I'd added tests for JDBC and CLI that I *thought* used SSL but they didn't! I wasn't careful...

Testing changes:
* Actually enable SSL/HTTPS in the `qa:sql:security:ssl` subproject.
* Rework how `RemoteCli` handles security. This allows us to configure SSL, the keystore, and the username and password in a much less error prone way.
* Fix up JDBC tests to properly use SSL.
* Allow the `CliFixture` to specify the keystore location.
* Switch `CliFixture` and `RemoteCli` from sending the password in the connection string to filling out the prompt for it.
* Have `CliFixture` also send the keystore password when a keystore is configured.

This makes the following production code changes:
* Allow the CLI to configure the keystore location with the `-k`/`-keystore_location` parameters.
* If the keystore location is configured then the CLI will prompt for the password.
* Allow the configuration of urls starting with `https`.
* Improve the exception thrown when the URL doesn't parse by adding a suppressed exception with the original parse error, before we tried to add `http://` to the front of it.

to retrieve data for analysis.

Alexander Reelsen eaf67f8bc2 Tests: Replace YAML tests with ESTestRestCase to be able to wait for … (elastic/x-pack-elasticsearch#3252)
* Tests: Replace YAML tests with ESTestRestCase to be able to wait for events

The YAML tests did not have any possibility to wait for the watches to
be created. A hard ten second timeout was used, that could not be
aborted, by simulating a sleep when waiting for a number of nodes that
never occured in the cluster.

This commit replaces those waiting YAML tests with ESRestTestCases, that
use `assertBusy()` to exit early once the watches have been added. Also
this increases the wait time if needed, as these tests tend to fail on
CI.

javanna 08950ff491 Remove security filter, replaced by get index api call which returns filtered mappings
Given that we get now filtered mappings directly from the get index API (in case security is configured with FLS), we don't need the security filter nor the filtered catalog. That means we can remove the delayed action support also from AuthorizationService and rather make SQLAction a composite action like others. It will be authorized as an action, but its indices won't be checked while that will happen with its inner actions (get index and search) which need to be properly authorized.

Also, SQLGetIndicesAction is not needed anymore, as its purpose was to retrieve the indices access resolver put in the context by the security plugin for delayed actions, which are not supported anymore.

This commit kind of reverts elastic/x-pack-elasticsearch#2162, as it is now possible to integrate with security out-of-the-box

Costin Leau 7cab29760d SQL: Introduce PreAnalyze phase to resolve catalogs async (elastic/x-pack-elasticsearch#2962)
SQL: Introduce PreAnalyze phase to resolve catalogs async

The new preanalyze phase collects all unresolved relations and tries
to resolve them as indices through typical async calls _before_ starting the analysis process.
The result is loaded into a catalog which is then passed to the analyzer.
While at it, the analyzer was made singleton and state across the engine
is done through SqlSession#currentContext().


Commit missing fix
Fix typo
Fix license
Fix line length
remove redundant static modifier
Remove redundant generics type
Rename catalogResolver instance member to indexResolver
Fix translate action to return a response through the listener, it hangs otherwise
IndexResolver improvements

Make sure that get index requests calls are locally executed by providing local flag.
Don't replace index/alias name with concrete index name in asCatalog response conversion. We need to preserve the original alias name for security, so it is reused in the subsequent search.
Update roles and actions names for security tests
Get index is now executed instead of sql get indices, and sql get indices has been removed.
Also made cluster privileges more restrictive to make sure that cluster state calls are no longer executed.
Fix most of the security IT tests
indices options are now unified, always lenient. The only situation where we get authorization exception back is when the user is not authorized for the sql action (besides for which indices).
Improve SessionContext handling
Fix context being invalid in non-executable phases
Make Explain & Debug command fully async
Resolve checkstyle error about redundant modifiers
Temporarily restore SqlGetIndicesAction

SqlGetIndicesAction action is still needed in RestSqlJdbcAction (metaTable and metaColumn methods), where we can't at the moment call IndexResolver directly, as security (FLS) needs index resolver to be called as part of the execution of an indices action. Once mappings are returned filtered, delayed action and the security filter will go away, as well as SqlGetIndicesAction.
SqlGetIndicesAction doesn't need to be a delayed action, my bad

In order to support the repository split, this changes the

We have a dedicated QA project called `smoke-test-watcher-with-security`,

This commit removes the possibility to enable security as part of the
test case. In addition some tests have been moved over to the dedicated
project.

In addition the `timewarp` functionality cannot be configured with a
system property anymore. This would not have worked anyway, because
tests were already dependent on that  functionality and did not have any
other means of running. A bit of redundant code was removed due to this.

Alexander Reelsen 6406c9816a Watcher: Add transform input for chained input (elastic/x-pack-elasticsearch#2861)
The chained input in watcher is a useful feature to
call several endpoints before execution a condition.
However it was pretty hard to modify data from a previous
input in order to be able to execute it in another input.

This commit adds a another input, called a `transform` input,
which allows you to do a transform as another input in a chained
input.

See this example

```
"input" : {
  "chain" : {
    "inputs" : [ <1>
      {
        "first" : {
          "simple" : { "path" : "/_search" }
        }
      },
      {
        "second" : {
          "transform" : {
            "script" : "return [ 'path' : 'ctx.payload.first.path' + '/' ]"
          }
        }
      },
      {
        "third" : {
          "http" : {
            "request" : {
              "host" : "localhost",
              "port" : 9200,
              "path" : "{{ctx.payload.second.path}}" <2>
            }
          }
        }
      }
    ]
  }
}
```

This allows for far more flexibility before executing the next input in a chained
one.

Upon loading the watch the headers are loaded and applied for the
following watcher execution features

* search transform
* search input
* index action

A special case is the execute watch API, which overrides the headers loaded
from the watch with the one of the current request, so that a user
cannot execute this watch with other privileges of the user who stored it.

Only the headers "es-security-runas-user", "_xpack_security_authentication" are
copied for now, as those are needed for our security features.

The headers are stored in watch status in the watch and are not returned by default,
when the GET Watch API is used. A search reveals those of course.
