[pescetto]

• Filled out the rest of the Device struct.
• Add the function GetDevices to return a list of bigip devices in the cluster.
• Add a test for the new function

@scshitole when you have a chance, this PR is ready for review.

@scshitole this looks useful, can we have this merged?

@pescetto I think the device PR broke the test for CmDevice

I also don't see that test at all on master:

$ grep 'TestAccBigipCmDevice' -r ./                                                                                                                                     
$

Is that a new test you're adding? It might be easier chatting in the slack room if you're on the f5CloudSolutions workspace.
