inlineoverridevirtual

Verify that host is a valid metadata server.

Exceptions

MySQLSession::Error
std::runtime_error
std::out_of_range
std::logic_error

checks that the server

• has the metadata in the correct version
• contains metadata for the group it's in (in case of GR cluster) (metadata server group must be same as managed group currently)

Reimplemented from mysqlrouter::ClusterMetadata.
