After asynchronously fetching shard information the gateway allocator issues a reroute via a cluster state update task. #11421 introduced an optimization trying to avoid submitting unneeded reroutes when results for many shards come in together. This is done by having a rerouting flag, indicating a pending reroute is coming and thus any new incoming shard info doesn't need to issue a reroute. This flag wasn't reset upon an error in the reroute update task. Most notably - if a master node had to step during to a min_master_node violation, it could reject an ongoing reroute. Lacking to reset the flag causing it to skip any future reroute, when the node became master again.
Closes#11519
Since we are creating write.lock earlier now, blob store shouldn't attempt deleting this file during clean up at the end of the restore process. The file is locked and the blog store doesn't succeed, but it generates a lot of useless warnings "failed to delete file [write.lock] during snapshot cleanup".

## Release Notes - Maven Assembly Plugin - Version 2.5.5
* Bug
- [MASSEMBLY-767] - Schema missing from the web site
- [MASSEMBLY-768] - JarInputStream unable to find manifest
created by version 2.5.4
- [MASSEMBLY-769] - ZIP fileMode permissions not properly set with
dependencySet and unpackOptions
Some of our meta fields (such as _id, _version, ...) are returned as top-level
properties of the json document, while other properties (_timestamp, _routing,
...) are returned under `fields`. This commit makes all meta fields returned
as top-level properties.
So eg. `GET test/test/1?fields=_timestamp,foo` would now return
```json
{
"_index": "test",
"_type": "test",
"_id": "1",
"_version": 1,
"_timestamp": 10000000,
"found": true,
"fields": {
"foo": [ "bar" ]
}
}
```
while it used to return
```json
{
"_index": "test",
"_type": "test",
"_id": "1",
"_version": 1,
"found": true,
"fields": {
"_timestamp": 10000000,
"foo": [ "bar" ]
}
}
```
To protect ourselves against running blocking operations on a network thread we have added an assertion that triggers that verifies that the thread calling a BaseFuture.get() is not a networking one. While this assert is good, it wrongly triggers when the get() is called in order to pass it's result to a listener of AbstractListenableActionFuture who is marked to run on the same thread as the callee. At that point, we know that the operation has been completed and the get() call will not block.
To solve this, we change the assertion to ignore a get with a timeout of 0 and use that AbstractListenableActionFuture

In rare occasion, the translog replay phase of recovery may require mapping changes on the target shard. This can happen where indexing on the primary introduces new mappings while the recovery is in phase1. If the source node processes the new mapping from the master, allowing the indexing to proceed, before the target node does and the recovery moves to the phase 2 (translog replay) before as well, the translog operations arriving on the target node may miss the mapping changes. To protect agains this we now throw and catch an exception, so we can properly wait and retry when the next cluster state arrives.
