While conceptually correct this call can be confusing since if a
realtime GET is exectued after refresh is called with realtime=true it might
fetch the wrong document out of the translog since the isRefreshNeeded guard
might return false once the new searcher is published but it will not
wait until the verision map is flushed and that can cause a slight race condition
if a subsequent call GETs a document that it expects to come from the index.
Ie. the `_size` mapper tests do this and expecte the GET call to return the document
from the index but it comes from the t-log due to this race.
This change only uses the guard in an async refresh that we schedule to prevent unnecessary
refresh calls but will allow API Refresh calls to have the somewhat less confusing semantics.
This was introduces lately only on unrelease major version branches.
This is consistent with what happens in elasticsearch.sh/.bat, and it means
tests will work even if there is a crazy "system" JNA installed on the machine.
This commit allows an integ test to wrap all clients that are exposed by the
InternalTestCluster which is useful for request interception or to add general headers
to request or to intercept client to server call even if the client calls are done from within
the test framework.

Exceptions (throw, try/catch)

Documentation:
Added JavaDocs for some files
Today the TransportClient uses the given settings rather than the updated setting from the plugin
service to pass on to it's modules etc. It should use the updates settings instead.
Today we already validate all index level setting on startup. For global
settings we are not fully there yet since not all settings are registered.
Yet we can already validate the ones that are know if their values are parseable/correct.
This is better than nothing and an improvement to what we had before. Over time there will
be more an dmore setting converted and we can finally flip the switch.
One test we forgot in #14843 and #13779 is the default client selection.
Most of the time, users won't define explicitly which client they want to use because they are providing only one connection to Azure storage:
```yml
cloud:
azure:
storage:
my_account:
account: your_azure_storage_account
key: your_azure_storage_key
```
Then using the default client like this:
```sh
# This one will use the default account (my_account1)
curl -XPUT localhost:9200/_snapshot/my_backup1?pretty -d '{
"type": "azure"
}'
```
This commit adds tests to check that the right client is still selected when no client is explicitly set when creating the snapshot.
This commit replaces server side timeout (which is BTW not correctly implemented in azure client 2.0.0 but fixed later #16084) with a client side timeout.
As a consequence, for each request sent to azure, azure client will raise an exception after a given amount of time (timeout).
Closes#12567
Cut over all index scope settings to the new setting infrastrucuture
This change moves all index.* settings over to the new infrastructure. This means in short that:
- every setting that has an index scope must be registered up-front
- index settings are validated on index creation, template creation, index settings update
- node level settings starting with index.* are validated on node startup
- settings that are private to ES like index.version.created can only be set by tests when they install a specific test plugin.
- all index settings can be reset by passing null as their value on update
- all index settings defaults can be listed via the settings APIs

This commit adds handling of channel failures when starting a shard to
o.e.c.a.s.ShardStateAction. This means that shard started requests
that timeout or occur when there is no master or the master leaves
after the request is sent will now be retried from here. The listener
for a shard state request will now only be notified upon successful
completion of the shard state request, or when a catastrophic
non-channel failure occurs.
This commit also refactors the handling of shard failure requests so
that the two shard state actions of shard failure and shard started
now share the same channel-retry and notification logic.
This commit fixes an issue in the handling of TransportExceptions in
ShardStateAction. There were two cases not being handled correctly.
- when the local node is shutting down, handlers will be notified with
a TransportException with a message starting "transport stopped"
- when the remote node disconnects, handlers will be notified with a
NodeDisconnectedException
In both of these cases, the cause of the exception will be null and this
was incorrectly being handled. The first case can passed to the listener
like any other critical non-channel failure, and the second case can be
handled by modifying the logic for detecting master channel exceptions.
There was a third case of NodeNotConnectedException that was not being
treated as a master channel exception but should be.
This commit adds an integration test that simulates the handling of a
shard failure request during a network partition. By isolating the
master from the cluster while a shard failed request is in flight, this
test simulates that we wait until a new master is elected and then retry
sending that shard failed request to the newly elected master.
This commit adds methods to CapturingTransport to separate local and
remote transport exceptions. The motivation for this change is that
local transport exceptions are delivered to listeners (usually, but not
always) wrapped in SendRequestTransportException while remote transport
exceptions are delivered to listeners wrapped in
RemoteTransportException. By making this distinction clear in the
CapturingTransport, this makes it less likely that tests will make
incorrect assumptions about the exceptions coming out of the transport
layer to listeners.
