Commit Message

Dmitry Safonov Oct. 27, 2022, 8:43 p.m. UTC 
Use -X to set md5 password string and -M to set authentication method as
TCP-MD5. Remove client_pw as not needed. This will allow to add an
option to use TCP-AO as authentication method.
Note, that use_md5 is a bit, rather than an enum member like
`authentication_method` - this will allow to call nettest the way that
it'll try to connect with both tcp-md5 and tcp-ao setsocketopt()
[which shouldn't be allowed].
