With this commit we revert the default value for the setting
'index.requests.cache.enable' again to false, which has been
set to true by accident in PR #16054.

Note for many of the settings we had a netty specific override to a generic transport setting. I have removed those as they are not needed imo (ex. "transport.connections_per_node.recovery" was overriden by "transport.netty.connections_per_node.recovery", which I removed). The netty prefix was kept for settings that are tied to the netty universe - ex. "transport.netty.max_cumulation_buffer_capacity"
Closes#16200
Today our logger settings are treated differently than all other
settings. This was a shortcut / workaround since it's quite messy but now
that we have strict validation and transactional updates we should integrate the
logger settings there as well. This commit makes the logger settings a build-in
settings updater and removes all the special code-paths we had for these settings.
Logger settings now also updateable and resetttable by passing `null`
In the early days Elasticsearch used to use the index name as the index identity. Around 1.0.0 we introduced a unique index uuid which is stored in the index setting. Since then we used that uuid in a few places but it is by far not the main identifier when working with indices, partially because it's not always readily available in all places.
This PR start to make a move in the direction of using uuids instead of name by making sure that the uuid is available on the Index class (currently just a wrapper around the name) and as such also available via ShardRouting and ShardId.
Note that this is by no means an attempt to do the right thing with the uuid in all places. In almost all places it falls back to the name based comparison that was done before. It is meant as a first step towards slowly improving the situation.
Closes#16217
Adds unit tests for blob operations and integration tests for repository operations. These tests can be used by repository plugins to verify that repository operations were implemented as expected by BlobStoreRepository.
We used to have a disabled test around cluster put settings as it left cluster settings behind without a way to remove them. That has been in fixed in the cluster put settings api, so the test can be re-enabled.
