Allow for enabling or disabling of cube rules

[nicolasbisurgi]

Describe the bug
TM1Py should have a function to toggle on or off a cube rule. This could be useful when performing bulk loads of data into rule based cubes. Similarly to CubeLogging you can disable rules (if you don't need them to process at load time), load your data, and then enabling them back.

Expected behavior
Rules should be commented our entirely and then uncommented back, always respecting prior/real comments.

Version
TM1py [e.g. 1.3.1]
TM1 Server Version: [e.g. 11.4]
