regulators: Create TemporaryFile class

Create class for handling temporary files:
* Constructor creates the temporary file
* Destructor deletes the temporary file
* Provides move constructor and move assignment operator so that class
  can be stored in containers like std::vector
* Throws exception if errors occur creating or deleting the temporary file

This class is an enhanced version of the TmpFile class in the test
directory.  A future commit will delete TmpFile and modify testcases to
use TemporaryFile instead.

Tested:
* Created automated tests for most of the code in the class.
* Manually tested some error cases that were difficult to automate.
