g-cli did not show any warnings or errors when using the deprecated (2.x) --timeout argument

I have a build that used the g-cli 2.x and was utilizing the --timeout argument, which has been renamed --connect-timeout. I was getting build errors that g-cli was timing out connecting and that seemed odd. I then did a g-cli --help and noticed there was no --timeout argument and it took me a few scans of the list of args to realize that it had been renamed.

Things that would have helped me (just a few ideas):

• support the deprecated argument names as aliases to the new argument names
• show a deprecation warning when using deprecated arguments
• show a warning or error message when g-cli receives and unknown argument

Thanks!

Hmm this should already be aliased, I'll added some testing in case the aliasing is broken and see if I can detect it and generate a warning
