Add ingress category to civo marketplace

[milindchawre]

Add separate category for ingress in civo marketplace.

Putting all ingress controllers in same category make it easy:

• to detect different available options, right now these are scattered across different categories.
• to have temporary mechanism to prevent mutual exclusive controllers getting installed.

So far I see these Ingress Controllers: Haproxy, Traefik, Traefik v2, nginx, ambassador edge stack, gloo edge.

Sounds reasonable to me, but @saiyam1814 is running the marketplace so it's his call :-)

Agree, we have a reasonable number of Ingress Controllers on Civo Marketplace so I agree to have a separate section for Ingress. We have 6 and one more PR raised for Kond by @milindchawre

It's been a while I have revisited this issue. It seems all the ingress controllers apps are under architecture category and it has got quiet crowded.
