Subject: [PATCH] Create script for uploading ssh pubkey to Gerrit

'gerrit-auth.sh' takes a single argument of an ssh public-key file to be
added to the sandbox user in Gerrit. This way users don't need to go
through an error-prone setup of copy & pasting the curl command. Some
explainations of curl errors are also provided.
