My understanding of the problem -

Some unknown trigger causes a password to appear for SSH Keyfile in the 
gerrit-trigger plugin:

https://build.gluster.org/gerrit-trigger/server/review.gluster.org/

We do not need password for the SSH keyfile to connect to gerrit and 
presence of a password results in a connection failure. If you cleanup 
the password and attempt a connection, it works. However saving the 
configuration after clearing the password doesn't seem to work as the 
password does not get cleared in the URL listed above. A jenkins restart 
might help.

gerrit-trigger seems to inherit this password from the configured 
credentials and am not entirely certain about why/how the credentials 
configuration came about.

Sending this across for future reference. Kaushal and/or Misc might have 
better ideas than me as far as this problem is concerned.
