Added new AckedClusterStateUpdateTask interface that can be used to submit cluster state update tasks and allows actions to be notified back when a set of (configurable) nodes have acknowledged the cluster state update. Supports a configurable timeout, so that we wait for acknowledgement for a limited amount of time (will be provided in the request as it curently happens, default 10s).
Internally, a low level AckListener is created (InternalClusterService) and passed to the publish method, so that it can be notified whenever each node responds to the publish request. Once all the expected nodes have responded or the timeoeout has expired, the AckListener notifies the action which will return adding the proper acknowledged flag to the response.
Ideally, this new mechanism will gradually replace the existing ones based on custom endpoints and notifications (per api).

The suggest stop filter is an improved version of the stop filter, which
takes stopwords only into account if the last char of a query is a
whitespace. This allows you to keep stopwords, but to allow suggesting for
"a".
Example: Index document content "a word". You are now able to suggest for
"a" and get back results in the completion suggester, if the suggest stop
filter is used on the query side, but will not get back any results for
"a " as this is identified as a stopword.
The implementation allows to set the `remove_trailing` parameter for a
custom stop filter and thus use the suggest stop filter instead of the
standard stop filter.
remove usage of if and () blocks as they clashed with user paths containing ()
postpone quotation of variables to prevent double escaping ("")
fix#3906
(cherry picked from commit 1cc095ec32a5b623f88c312f497ac5469887be97)
- "boost" should be "boost_factor"
- "mult" should be "multiply"
Also, store combine function names in ImmutableMap instead of iterating
over all possible names each time.

SynonymFilters produces token streams with stacked tokens such that
conjunction queries need to be parsed in a special way such that the
stacked tokens are added as an innner disjuncition.
Closes#3881
The array holding the payloads (TermVectorFields.payloads) is reused for each token. If the
previous token had payloads but the current token had not, then the payloads of the previous
token were returned, because the payloads of the previous token were never invalidated.
For example, for a field only contained two tokens each occurring once, the first having a
payload and the second not, then for the second token, the payload of the first was returned.
closes#3873
Extended the specialized simplified mapping source method to support metadata mapping fields. These fields can just specified as normal fields, but will automatically be placed as top level mapping field.
Closes#3818
Return a merge_id element in each segment of the segments API, allowing to group segments that are being merged as part of a single merge and indicate which ones are being merged now.

Some tests use AbstractIntegrationTest#indexRandom which sometimes uses async
indexing. This can easily run into queue size based rejections on a slow
box. In that case we should retry blocked indexing.
Now that we properly fixed the ability to set the queue size on the index / bulk thread pool, we should actually set them to a somehow reasonable value to protect from users potentially overflowing our system.
I suggest defaults to be 50 for bulk, and 200 for indexing.
Also, set the thread pool for get, which we should set (in a similar value to a "read" queue size we have today).

We want to make sure that Plugin Manager still downloading plugins from internet.
New tests requires internet access (`@Network` annotation has been added).
By default, tests annotated with `@Network` are not launched.
If you need to run these tests, use `-Dtests.network=true` option.
Closes#3894.
