This change adds support for to put the watcher user in the context that is passed to the
ScriptService when Shield is installed and watcher integration with Shield is enabled.

This includes the following:
- Updated .gitignore to be the same as the elasticsearch repo so eclipse files are correctly ignored
- Fixes ambiguous method call compile error in HipChatMessageTests

This commit adds a test to ensure that all request handlers are wrapped
by ProfileSecuredRequestHandler.
Original commit: elastic/x-pack-elasticsearch@26473d0ddc
Currently we copy the authorization header from every rest request to the action request. This is not
necessary because the user associated with each request is copied into the context and then if the
request leaves the node, the user will be serialized into a string and attached as a header.
This commit removes the copying of the authorization header as it is not necessary and by not copying
it, we limit the amount of copies we make of this sensitive information.

This commit adds document and field level security to Shield.
Field level security can be enabled by adding the `fields` option to a role in the `role.yml` file.
For example:
```yaml
customer_care:
indices:
'*':
privileges: read
fields:
- issue_id
- description
- customer_handle
- customer_email
- customer_address
- customer_phone
```
The `fields` list is an inclusive list of fields that controls what fields should be accessible for that role. By default all meta fields (_uid, _type, _source, _ttl etc) are also included, otherwise ES or specific features stop working. The `_all` field if configured, isn't included by default, since that actually contains data from all the other fields. If the `_all` field is required then this needs to be added to the `fields` list in a role. In the case of the content of the `_source` field and `_field_names` there is special filtering in place so that only the content relevant for the role are being returned.
If no `fields` is specified then field level security is disabled for that role and all fields in an index are accessible.
Field level security can be setup per index group.
Field level security is implemented at the Lucene level by wrapping a directory index reader and hides fields away that aren't in the `field` list defined with the role of the current user. It as if the other fields never existed.
* Any `realtime` read operation from the translog is disabled. Instead this operations fall back to the Lucene index, which makes these operations compatible with field level security, but there aren't realtime.
* If user with role A executes first and the result gets cached and then a user with role B executes the same query results from the query executed with role A would be returned. This is bad and therefore the query cache is disabled.
* For the same reason the request cache is also disabled.
* The update API is blocked. An update request needs to be executed via a role that doesn't have field level security enabled.
Document level security can be enabled by adding the `query` option to a role in the `role.yml` file:
```yaml
customer_care:
indices:
'*':
privileges: read
query:
term:
department_id: 12
```
Document level security is implemented as a filter that filters out documents there don't match with the query. This is like index aliases, but better, because the role query is embedded on the lowest level possible in ES (Engine level) and on all places the acquire an IndexSearcher the role query will always be included. While alias filters are applied at a higher level (after the searcher has been acquired)
Document level security can be setup per index group.
Right now like alias filters the document level security isn't applied on all APIs. Like for example the get api, term vector api, which ignore the alias filter. These apis do acquire an IndexSearcher, but don't use the IndexSearcher itself and directly use the index reader to access the inverted index and there for bypassing the role query. If it is required to these apis need document level security too the the implementation for document level security needs to change.
