Fix spacing issues (4->2) in Middleware Topology js ctrl spec

[mtho11]

Fix the spacing issues in #8642 by reformatting from 4 to 2 spaces.

BTW: I noticed spacing issues in other js files as well ;)
Maybe at some point we might just want to do a global reformat of the js files. If we just did spacing the history diffs should still be good.

LGTM.
@mtho11 yes, the old code has still formatting issues on frontend and backend.
it is up to frontend maintainers to decide whether to do this major formatting pass on all the files.
@martinpovolny your thoughts on the topic?

@mtho11: we can make global reformat once we setup some lint checker for javascript to run on each PR. For now we can at least keep the formating.

@himdel : what's the status of a javascript style guide for ManageIQ and lint checker?

@martinpovolny Currently, the guide not so much, but as for the actual checking, I just need to comb through the rulesets.. should be relatively easy to just add the config files so that a check can be run manually. And as for miq-bot support - I have a testing environment set up and some begginings of the patch . . well, if I bumb up the priority, shouldn't take more than a few days..

@himdel : can you, please, put the current rules in a document in some informal way at least? I mean create a document such as the I18n guide and put the most obvious rules there, like the avoidance of global variables and size of indent. We need to be able to refer people somewhere. Maybe a reference to a javascript file that is well formatted to start with.

Will do.. a draft is available at #8781
