Describe the bug

Pyinfra is not processing comments in the ./ssh/config properly

To Reproduce

Put comments behind a line like " IdentityFile ~/.ssh/pyinfra_user_key # example comment"

The result of running pyinfra:
--> Connecting to hosts...
[127.0.0.1] Could not connect ([Errno 2] No such file or directory: '/home/martijn/.ssh/pyinfra_user_key # your private key')

Expected behavior

If I can ssh with a username like pyinfra (in my case via an open ssh CA signed key) then I expect that pyinfra will also work ... but that is not the case (not only comments are an issue, I've seen multiple things going working in the past days working with pyinfra)

Meta

Well this is simple enough to reproduce I guess.
I've fixed it by removing the comments. So pyinfra is usuable ... however it could be made more robust
