Add a cluster setting to disallow expensive queries (#51385) (#52279) 
Add a new cluster setting `search.allow_expensive_queries` which by
default is `true`. If set to `false`, certain queries that have
usually slow performance cannot be executed and an error message
is returned.

- Queries that need to do linear scans to identify matches:
  - Script queries
- Queries that have a high up-front cost:
  - Fuzzy queries
  - Regexp queries
  - Prefix queries (without index_prefixes enabled
  - Wildcard queries
  - Range queries on text and keyword fields
- Joining queries
  - HasParent queries
  - HasChild queries
  - ParentId queries
  - Nested queries
- Queries on deprecated 6.x geo shapes (using PrefixTree implementation)
- Queries that may have a high per-document cost:
  - Script score queries
  - Percolate queries

Closes: #29050
