Add configuration for packages version

[iustinam]

• allow installation of specific packages versions

[iustinam]

Could this feature be added ?

[javierbertoli]

Seems a useful parameter to add, which will complement #293/#314.

I see there's also a pkg resource in the proxy.sls file, that seems you missed. Can you add that one too?

[iustinam]

@javierbertoli I fail to find that file or any other pkg states referring to salt packages..
Isn't #314 enough? That seems more appropriate since the repo needs to match first..

[javierbertoli]

@iustinam, re: the proxy.sls file, ignore it. I grep'ed on a dirty local repo, and that file showed. My bad.

Re #314: I think both PRs complement each other: I agree that, usually, #314 will be enough. But that is true only if you use Saltstack's repo and want to pin the repo's version.

But even then, there are a few situations where your PR make sense, ie:

• You want to use the Saltstack's repo, but you want to pin packages so they're not upgraded without your control
• You have Saltstack's repo configured, but you want to use another version of the Salt packages, ie, thosse in the distro's repos.
• You have more than a single distro's repo configured (stable, testing, etc) and want to pin the package version to use.

@aboe76, wdyt? I'm OK with merging this PR.

Looks good

@javierbertoli I agree with your logic.

[iustinam]

I just added an example in pillar.example
