Optional support for getAllIndexMetadata by index pattern #682

Description

FlintIndexMetadataService used to use index pattern (using wildcard character *) to fetch index metadata for indexes matching the pattern. This change makes supporting getting by pattern optional. Instead, the service could fetch index metadata for full index names.

This does not change the FlintSpark.describeIndexes api, which still takes an index pattern as argument.

Alternative Considered

Alternative is to not use index pattern in FlintIndexMetadataService.getAllIndexMetadata at all, and instead always take full index names. However, this adds number of requests overhead for services that do allow for pattern matching, e.g. OpenSearch implementation FlintOpenSearchIndexMetadataService. Instead of making 1 request, a pattern that matches to N indexes would require N requests to fetch their metadata, if getting by pattern is removed completely.
