Provide a way to query parameters with a category

[drewj-tp]

In order to do better rotation of assembly / block parameters, we need a way to find out what parameters are rotatable. The plan proposed in #1860 // #1877, I propose a new category rotatable for parameters.

We don't have a simple way to check if a parameter has a given category. Something like Parameter.atLocation

armi/armi/reactor/parameters/parameterDefinitions.py

Lines 420 to 422 in abd1db4

	def atLocation(self, loc):
	"""True if parameter is defined at location."""
	return self.location and self.location & loc

A corollary would be something like Parameter.hasCategory? Uses could check Parameter.categories but let's make something a little simpler

Drew and I talked about this, and I think it seems like a fine feature.

I'm on board.
