Support autenticate with private key without have too make an Putty Session

[marcomsousa]

mRemoteNG should support that we put the URI file to the private key directly in the conexions tab.

Expected Behavior

mRemoteNG should support that we put the URI to the private key directly in the connections tab.
It's a very common and more secury authentication in Linux.

Current Behavior

1. Create a new conexion
2. Change name, protocol, and username
3. Open putty, configure pointing to private key, save with the same name before
4. Change session in mRemoteNG to the same same has before.
5. Save backup (don't have the part in putty)

Possible Solution

mRemoteNG should support that we put the URI file to the private key directly in the conexions tab.

Context

I have a lot of VM and we authenticate with private keys, not passwords. (SSH v2)
So, we have more than 200 VMs and we need to have almost 200 putty sessions.

Your Environment

• Windows
• Remote -> Linux ssh with private keys

If we could, while we're at it, make this suggested field with variable support, then we could also use that field for external tools. I opened up a dedicated issue #2046 about this before finding this issue.
