Adds support for discrete, temporary, metastores inlined with queries called over arrow flight. These can be used to resolve identifiers parsed from the query in an ad-hoc manner.
How
introduce a MemoryStore and implement all store traits for it
encapsulate the ListSchemaResponse from regular clade metastore in a new message called InlineMetastoreCommandStatementQuery that also holds the query
now when get_sql_info is called arrow fails to pattern match against known commands and uses the fallback method
there we simply instantiate the MemoryStore for a one-off context that serves the query
