Source postgres: Validate SSH key before checking connection.

[alafanechere]

If an invalid SSH key (not RSA format, typo during copy paste etc) is used the failure happens at connection check:
Cannot invoke "org.bouncycastle.openssl.PEMKeyPair.getPublicKeyInfo()" because "keypair" is null

It would be great if we could validate the SSH key in the front-end with regex patterns.

We should validate this as part of the CHECK command

@ryankfu is this a duplicate that will be resolved by your recent PR? #18041

[ryankfu]

@akashkulk yes, this appears to have been fixed with the recent PR #18041 at least based on the changes from Rodi's PR which changes the retrieval method from getPublicKeyInfo() to keyPairs.iterator().next()

I will close this ticket as completed and update #18041 to include a description with this comment
