git-p4: add --no-verify option

Add new command line option --no-verify:

Add a new command line option "--no-verify" to the Submit command of
git-p4.py.  This option will function in the spirit of the existing
--no-verify command line option found in git commit. It will cause the
P4 Submit function to ignore the existing p4-pre-submit.

Change the execution of the existing trigger p4-pre-submit to honor the
--no-verify option. Before exiting on failure of this hook, display
text to the user explaining which hook has failed and the impact
of using the --no-verify option.

Change the call of the p4-pre-submit hook to use the new run_git_hook
function. This is in preparation of additional hooks to be added.

+
 The `p4-pre-submit` hook is executed if it exists and is executable.
 The hook takes no parameters and nothing from standard input. Exiting with
 non-zero status from this script prevents `git-p4 submit` from launching.
+It can be bypassed with the `--no-verify` command line option.
 
 One usage scenario is to run unit tests in the hook.
