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.

The action condition feature was carefully hidden in an example.
This commit creates an own paragraph to highlight this feature better.

The path of a JIRA endpoint used to be fixed. This commit allows the
path to be dynamic, so that users can deploy their JIRA instance under
an arbitrary prefix.

This is related to elastic/x-pack-elasticsearch#1217. This PR removes the default password of
"changeme" from the reserved users.
This PR adds special behavior for authenticating the reserved users. No
ReservedRealm user can be authenticated until its password is set. The
one exception to this is the elastic user. The elastic user can be
authenticated with an empty password if the action is a rest request
originating from localhost. In this scenario where an elastic user is
authenticated with a default password, it will have metadata indicating
that it is in setup mode. An elastic user in setup mode is only
authorized to execute a change password request.

This allows to configure a proxy for the reporting attachment
action. The proxy is used by the HTTP client.

As fields with underscores will be disallowed in master, and we have to
prepare the upgrade, this commit renames the _status field to status.
When the 5.x upgrade logic is in place in the 5.x we can remove all the
old style _status handling from the master branch.
Note: All the BWC compatibility tests, that load 5.x indices are now
faking a finished upgrade by adding the `status` field to the mapping
of the watches index.

The distribution of watches now happens on the node which holds the
watches index, instead of on the master node. This requires several
changes to the current implementation.
1. Running on shards and replicas
In order to run watches on the nodes with the watches index on its
primaries and replicas. To ensure that watches do not run twice, there is
a logic which checks the local shards, runs a murmurhash on the id and
runs modulo against the number of shards and replicas, this is the way to
find out, if a watch should run local. Reloading happens
2. Several master node actions moved to a HandledTransportAction, as they
are basically just aliases for indexing actions, among them the
put/delete/get watch actions, the acknowledgement action, the de/activate
actions
3. Stats action moved to a broadcast node action, because we potentially
have to query every node to get watcher statistics
4. Starting/Stopping watcher now is a master node action, which updates
the cluster state and then listeners acts on those. Because of this watches
can be running on two systems, if you those have different cluster state
versions, until the new watcher state is propagated
5. Watcher is started on all nodes now. With the exception of the ticker
schedule engine most classes do not need a lot of resources while running.
However they have to run, because of the execute watch API, which can hit
any node - it does not make sense to find the right shard for this watch
and only then execute (as this also has to work with a watch, that has not
been stored before)
6. By using a indexing operation listener, each storing of a watch now
parses the watch first and only stores on successful parsing
7. Execute watch API now uses the watcher threadpool for execution
8. Getting the number of watches for the stats now simply queries the
different execution engines, how many watches are scheduled, so this is
not doing a search anymore
There will be follow up commits on this one, mainly to ensure BWC compatibility.

* Adding limitations of Watch Edit page
* Removing image reference for now until image dir referencing is sorted out
* More end-user-friendly phrasing
* Language changes + bringing back image
Original commit: elastic/x-pack-elasticsearch@06bf93ee99
* Amending docs on security privileges required for Watcher
Previously, the watcher_user and watcher_admin roles did not exist so we documented the actual security privileges necessary. Now that these roles exist and encapsulate the security privileges, we update the documentation to refer to the roles instead.
* Breaking up sentences. Putting main content up front.
* Include triggered watches as well
* Emphasize read-only operations
