TCP server threads metrics (i.e. TCPThreads) is broken for <protocols> (over <tcp_port>/...) #80759
Description
In case of is used over <tcp_port> (e.t.c.), the name of the
server is different and the code in AsynchronouseMetrics.cpp fails to
match them.
Suggestion - add proper ServerType::Type enum into the ProtocolServerAdapter, and use
it over matching by "port name".
