Add channel filters to enhance the Search Packages function

[pozsgaic]

Describe the Enhancement:

[What you are trying to achieve that you can't?]
Efficiently view results from Search Packages and be able to filter out packages I'm not interested in.
We may consider other filters to use in addition to channels, such as target (e.g. x86_64-linux).

Describe the Need:

I would like to be able to see only the packages in a specified channel.
For example, I want to see only stable releases. I currently need to sift through versions manually
to find the stable releases.

[What kind of user do you believe would utilize this enhancement, and how many users might want this functionality]
I think most users would find this feature convenient.

Current Alternative

[Is there a current alternative that you can utilize to workaround the lack of this enhancement]

• From BuilderUI, search and find the desired package, load it, and manually identify the channels this package is loaded on.
• From command line, for the live builder, we would run:
  curl -X GET https://bldr.habitat.sh/v1/depot/channels/{origin}/{channel}/pkgs/{pkg}

Can We Help You Implement This?:

[The best way to ensure your enhancement is built is to help implement the enhancement yourself. If you're interested in helping out we'd love to give you a hand to make this possible. Let us know if there's something you need.]
