Added base TransportAction class for master read operations that execute locally or not depending on the request class (local flag).
Added support for local flag where missing, in a backwards compatible manner:
- IndicesExistsRequest
- GetAliasesRequest (get alias api, aliases exist api)
- TypesExistsRequest
- GetIndexTemplatesRequest (get template, template exists)
- GetSettingsRequest
- GetRepositoriesRequest
- PendingClusterTasks
Added parsing of the local flag where missing in Rest*Action.
Updated SPEC adding local flag param where missing and added REST tests that contain use of the local flag where it was just added.

Relates #4071
Currently there are two get aliases apis that both have the same functionality, but have a different response structure. The reason for having 2 apis is historic.
The GET _alias api was added in 0.90.x and is more efficient since it only sends the needed alias data from the cluster state between the master node and the node that received the request. In the GET _aliases api the complete cluster state is send to the node that received the request and then the right information is filtered out and send back to the client.
The GET _aliases api should be removed in favour for the alias api
