Plugin name list

Summary:
Adds an argument to the headless Flipper to print the list of available plugins. Added `--list-plugins`.

Currently the startFlipper function is not scalable enough to add new arguments and its implementation. I am planning to tackle this with the list of Actions which will be closure. So adding a new argument with its implementation will be just appending a closure at the correct location in an array. Will work on that in the later diff stacked on the current one.
