add wait for green to prevent test failure
Support for REST get ALL templates.
/_template shows: No handler found for uri [/_template] and method [GET]

It would make sense to list the templates as they are listed in the /_cluster/state call.

Closes #2532.
Remove get index templates deprecated methods
In 0.90.4, we deprecated some code:

* `GetIndexTemplatesRequest#GetIndexTemplatesRequest(String)` moved to `GetIndexTemplatesRequest#GetIndexTemplatesRequest(String...)`
* `GetIndexTemplatesRequest#name(String)` moved to `GetIndexTemplatesRequest#names(String...)`
* `GetIndexTemplatesRequest#name()` moved to `GetIndexTemplatesRequest#names()`

* `GetIndexTemplatesRequestBuilder#GetIndexTemplatesRequestBuilder(IndicesAdminClient, String)` moved to  `GetIndexTemplatesRequestBuilder#GetIndexTemplatesRequestBuilder(IndicesAdminClient, String...)`

* `IndicesAdminClient#prepareGetTemplates(String)` moved to `IndicesAdminClient#prepareGetTemplates(String...)`

* `AbstractIndicesAdminClient#prepareGetTemplates(String)` moved to `AbstractIndicesAdminClient#prepareGetTemplates(String...)`

We can now remove that old methods in 1.0.

**Note**: it breaks the Java API

Relative to #2532.
Closes #3681.
[DOCS] Added Cold Fusion client to community page
use trace logging on cluster state driven indexing
Removed wrong assertion that makes recoverWhileUnderLoadWithNodeShutdown fail.

As we are within an awaitBusy block, it doesn't make sense to have an assertion, since it would fail the test instead of waiting till the condition is verified (till timeout expires)
Improved test

Introduced ElasticsearchAssertions that check for failures in all response
Added comment to flush requests as we don't check for failures there
Attempt to remove Thread.sleep in testChangeInitialShardsRecovery in favour of awaitBusy block
Added awaitBusy block in testQuorumRecovery waiting for YELLOW. We could have GREEN after the close node but wa want to wait for the YELLOW state.
