What this PR does / why we need it:
This PR adds package level commands for And and Or to the TopologyManager socketmask abstraction. It also adds a new NewEmtpySocketMask() call to the API, so we can create empty socket masks that don't return an error. Finally, it cleans up the comments to make them more in line with go conventions.

The combination of the package level And and Or calls, together with the NewEmtpySocketMask() call will help to cleanup some of the code in the places where these socket masks are used.

Follow-up PRs will be created to address these.

Does this PR introduce a user-facing change?:

NONE

Hi @klueska. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
