Nicola Murino b2d3a6a4b4 ssh/agent: ensure to not add duplicated keys 
When adding a new key, if we already have a Signer with the same public
key, we now replace it with the new one instead of duplicating it.

Before this change we had this:

$ ssh-add -l
3072 SHA256:bsBRHC/xgiqBJdSuvSTNpJNLTISP/G356jNMCRYC5Es nicola@p1 (RSA)
3072 SHA256:bsBRHC/xgiqBJdSuvSTNpJNLTISP/G356jNMCRYC5Es nicola@p1 (RSA-CERT)

$ ssh-add /home/nicola/ssh_certs/id_rsa
Identity added: /home/nicola/ssh_certs/id_rsa (nicola@p1)
Certificate added: /home/nicola/ssh_certs/id_rsa-cert.pub (myid)

$ ssh-add -l
3072 SHA256:bsBRHC/xgiqBJdSuvSTNpJNLTISP/G356jNMCRYC5Es nicola@p1 (RSA)
3072 SHA256:bsBRHC/xgiqBJdSuvSTNpJNLTISP/G356jNMCRYC5Es nicola@p1 (RSA-CERT)
3072 SHA256:bsBRHC/xgiqBJdSuvSTNpJNLTISP/G356jNMCRYC5Es nicola@p1 (RSA)

Peter Moody 8e06e8ddd9 x/crypto/ssh/agent: honor constraints on keys in the keyring. 
If a key is added to an agent keyring with constraints, honor them.
This will remove keys when they've been on the keyring for
LifetimeSecs seconds or longer and will ask the user to confirm a
signing operation if ConfirmBeforeUse is set.

Mark Severson f18420efc3 x/crypto/ssh/agent: Fix keyring removing the wrong key(s) 
The Remove method for the keyring sliced the internal keys list
incorrectly when removing a key. This caused the wrong key to be removed
or sometimes multiple keys were removed. Additionally, if the key to be
removed was the last key, the method never returned.

Fixes golang/go#13628
