pmm-admin has a new socket option (--socket) that lets you specify what UNIX socket number is used to connect to MySQL instances for when you don't want to use a port number.

As a PMM User I need to specify socket for mysql to be used in pmm-admin add command so that PMM uses a socket instead of port

Use case:

pmm-admin add mysql .... --socket=....

Out Of Scope:

• web UI is not needed for remote instances
• Config file and reading socket from it will be implemented in PMM-5011
• API
  -----------

Currently, it is not possible to add mysql instance using UNIX socket option in PMM2.

It would be good to have --socket option in PMM2 as we have in PMM1 to add mysql instance using UNIX socket.

--socket flag should be string flag and should contain only path to socket without username, password and network type.

pmm-admin add mysql --socket=/var/path/to/mysql/socket

DOD:

pmm-admin add mysql and pmm-admin inventory add service mysql commands with --socket flag.
Value of --socket flag should be sent to API.
