Removes `testenv` annotations and related code. These annotations originally let you skip x-pack snippet tests in the docs. However, that's no longer possible.
Relates to #79309, #31619
This commit adds two related changes:
* ILM WaitForDataTierStep
* Autoscaling frozen_existence decider
The first part ensures that we wait mounting an index until a node that
can hold the index is available, avoiding a failed restore and red
cluster state. This is in particular important for the frozen phase, but
is done generically in the searchable snapshot action.
The second part triggers on indices in the ILM frozen phase to scale the
tier into existence by requiring a minimal amount of memory and storage.
Closes#72771
Fixed autoscaling docs to no longer call partially mounted indices or
shards for frozen indices/shards, now uses partially mounted indices or
shards.
Closes#73132

The frozen tier partially downloads shards only. This commit
introduces an autoscaling decider that scales the total storage
on the tier according to a configurable percentage relative to
the total data set size.
We no longer regard the autoscaling APIs experimental though they are
only intended for use by ESS/ECE/ECK. This commit updates the docs
to reflect this and adds a minimal set of documentation for the
feature.
