Voting config exclusions should work with absent nodes#55291

Today the voting config exclusions API accepts node filters and resolves them to a collection of node IDs against the current cluster membership. This is problematic since we may want to exclude nodes that are not currently members of the cluster. For instance: - if attempting to remove a flaky node from the cluster you cannot reliably exclude it from the voting configuration since it may not reliably be a member of the cluster - if `cluster.auto_shrink_voting_configuration: false` then naively shrinking the cluster will remove some nodes but will leaving their node IDs in the voting configuration. The only way to clean up the voting configuration is to grow the cluster back to its original size (potentially replacing some of the voting configuration) and then use the exclusions API. This commit adds an alternative API that accepts node names and node IDs but not node filters in general, and deprecates the current node-filters-based API. Relates elastic#47990.

the exception message has changed in elastic#55291. This is not covered by rest api compatibility, so no need to return the old message for v7 requests. This commit adds a transformation to allow for the 7.x test to pass with a new exception message relates elastic#51816

In elastic#55291 we deprecated the older form of the voting config exclusions API but forgot to record this deprecation in the docs. This commit adds the missing docs.

Today the voting config exclusions API accepts node filters and resolves them

This is problematic since we may want to exclude nodes that are not currently

Backport of #50836 to 7.x.
