Use default forceAnalyzeQueryString if no query builder is present

In the single field case no query builder is selected which causes NPE
when the query has only a numeric field.

Tie-break suggestions from phrase suggester by term

If the score for two suggestions is the same, we now tie break by term; earlier terms (aaa) sort before later terms (zzz).

[TEST] Stabelize MoreLikeThisActionTests

The `testCompareMoreLikeThisDSLWithAPI` test compares results from query
and API which might query different shards. Those shares might use
different doc IDs internally to disambiguate. This commit resorts the
results and compares them after stable disambiguation.

[DOCS] Cat recovery API update

This is an update for the _cat/recovery API documentation. The examples
have been updated. Removed the bottom paragraph explaining why there
could be values > 100%. This can no longer happen so that had to be
removed.

Closes #6159
lightweight minimum master node recovery
don't perform full recovery when minimum master nodes are not met, keep the state around and use it once elected as master
make no master lock an instance var so it can be configured
add rejoin on master gone flag, defaults to false
defaults to false since there is still work left to properly make it work
Make noMasterBlock configurable and added simple test that shows reads do execute (partially) when m_m_n isn't met
Enable `discovery.zen.rejoin_on_master_gone` setting in DiscoveryWithNetworkFailuresTests only.
Changed the default for the 'rejoin_on_master_gone' option from false to true in zen discovery.
Added AwaitFix for the FullRollingRestartTests.
If available newly elected master node should take over previous known nodes.
Fixed compile error
Do not start a recovery process if the primary shard is currently allocated on a node which is not part of the cluster state

If a source node disconnect during recover, the target node will respond by canceling the recovery. Typically the master will respond by removing the disconnected node from the cluster state, promoting another shard to become primary. This is sent it to all nodes and the target node will start recovering from the new primary. However, if the drop of a node caused the node count to go bellow min_master_node, the master will step down and will not promote shard immediately. When a new master is elected we may publish a new cluster state (who's point is to notify of a new master) which is not yet updated. This caused the node to start a recovery to a non existent node. Before we aborted the recovery without cleaning up the shard, causing subsequent correct cluster states to be ignored. We should not start the recovery process but wait for another cluster state to come in.
RoutingService background reroute task should check if node is still master when its run

It may be that between the moment the task was added to the queue the current node stepped down from being master (due to minimum_master_nodes settings).
Eagerly clean the routing table of shards that exist on nodes that are not in the latestDiscoNodes list.

Only the previous master node has been removed, so only shards allocated to that node will get failed.
This would have happened anyhow on later on when AllocationService#reroute is invoked (for example when a cluster setting changes or another cluster event),
but by cleaning the routing table pro-actively, the stale routing table is fixed sooner and therefor the shards
that are not accessible anyhow (because the node these shards were on has left the cluster) will get re-assigned sooner.
Use just AllocationService#reroute to eagerly clean the routing table of nodes that don't exist instead of using AllocationService#applyFailedShards directly.
Before a local unused shard copy, verify we're connected to the node it's supposed to be on

This is yet another safety guard to make sure we don't delete data if the local copy is the only one (even if it's not part of the cluster state any more)
