Scripting: Per-context script cache, default off (#52855) (#53756)
* Adds per context settings:
  `script.context.${CONTEXT}.cache_max_size` ~
  `script.cache.max_size`

  `script.context.${CONTEXT}.cache_expire` ~
  `script.cache.expire`

  `script.context.${CONTEXT}.max_compilations_rate` ~
  `script.max_compilations_rate`

* Context cache is used if:
  `script.max_compilations_rate=use-context`.  This
  value is dynamically updatable, so users can
  switch back to the general cache if desired.

* Settings for context caches take the first value
  that applies:
  1) Context specific settings if set, eg
     `script.context.ingest.cache_max_size`
  2) Correlated general setting is set to the non-default
     value, eg `script.cache.max_size`
  3) Context default

The reason for 2's inclusion is to allow an easy
transition for users who've customized their general
cache settings.

Using the general cache settings for the context caches
results in higher effective settings, since they are
multiplied across the number of contexts.  So a general
cache max size of 200 will become 200 * # of contexts.
However, this behavior it will avoid users snapping to a
value that is too low for them.
