Title: Changed mongod from a string to Regex for config arg inspection

When running the following command, I was getting the following error:

$ mongod --config=config/mongodb.conf
error command line: multiple occurrences
use --help for help

When diagnosing, it was because we are matching an explicit string `--config`. I've changed to a regex to accept the bash convention of "=" signs on arguments with double dashs.
