Add clickable links to Docker images

[applejag]

A bit of a goofy idea, and would only be as a "wouldn't it be cool if" kind of feature.

Expected Behavior

When doing kubectl describe, it would be nice if the Docker image name was a link to the registry.

This can be done via the OSC 8 escape sequence.

For example, the "Image" part of:

$ kubectl describe pods
...
Containers:
  trustmanager:
    Container ID:    containerd://b0151dd97058ba40968eec66d024795c762fba9365c106518f97d1b1c6183684
    Image:           quay.io/jetstack/trust-manager:v0.8.0
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this here

There's no way to really guess how to construct the links, so there's going to need some heuristic-based hardcoding (and potentially configurable later via ~/.kube/color.yaml file).

To begin with, it should know how to convert the following images to the following URLs:

Image	URL
quay.io/jetstack/trust-manager:v0.8.0	https://quay.io/repository/jetstack/trust-manager?tab=tags&tag=v0.8.0

Some links can't go directly to the exact tag or digest as you need more information to build the link than what you have available (such as Docker Hub links that need both image tag and digest to construct the URL). There can be future improvements to kubecolor that make this more exact.

Should also handle no tag as :latest

Current Behavior

Just displayed as (colored) text.
