Do not run these seeds twice

[isimluk]

We run seeds on every start-up. Certain methods were called twice. That is not efficient.

On my system, running 100.times { MiqWidget.seed } gives:

ms	bytes	objects	queries	query (ms)	%	comments
55,532.4	89,772,866*	61,866,274	31,300	13,085.5	100%	before
9,343.4	7,196,824*	8,821,284	6,300	2,181.3	16%	after

Checked commits isimluk/manageiq@49c07af~...3bc2be6 with ruby 2.2.6, rubocop 0.47.1, and haml-lint 0.20.0
2 files checked, 0 offenses detected
Everything looks good. 👍

Is there a way we can define these dependencies somewhere?

the dependencies will be hidden in our ordered list and if we want to remove primordial seeds, we won't be able to.

@Fryguy do you like just having comments in the seed ordering?

[Fryguy]

We could just hardcode the list right in the initial seeding if you want. I don't think we have to be super dynamic about seeding.
