Add Command-Line Option to Suppress Moose Information

[olinwc]

Motivation

Per the Griffin-MOOSE meeting discussion today, it is desirable to be able to suppress MOOSE information messages. While information messages can be very useful for first-time users or running an input for the first-time, when running variations of the same input they can become quite lengthy and cumbersome, particularly for very large problems.

Design

Add a new command-line option like --suppress-info or --disable-info to suppress info messages

Impact

New capability, no change needed for existing tests or inputs.
