[ReillyBrogan]

Support additional labels in the hubble-ui ingress definition.

Please ensure your pull request adheres to the following guidelines:

• For first time contributors, read Submitting a pull request
• All code is covered by unit and/or runtime tests where feasible.
• All commits contain a well written commit description including a title,
  description and a Fixes: #XXX line if the commit addresses a particular
  GitHub issue.
• If your commit description contains a Fixes: <commit-id> tag, then
  please add the commit author[s] as reviewer[s] to this issue.

Some Ingress controllers (Traefik for example) support using labels for selecting which ingresses to serve from a particular ingress controller. This adds support for that.

@ReillyBrogan Could you rebase this branch on master? It seems to be lagging a bit behind, thereby causing some CI failures due to tests requiring a more recent code base. Thanks.

Looking good! Let's run CI
