Support multi ssh-keys in git client

[funera1]

What would you like to be added:
Allow multi ssh-keys information to be entered in the Git field of the Piped configuration. However, the interface should be compatible with the previous version.

Why is this needed:
Some repositories may not be able to access one ssh-key.
