feat: Add path-based Ingress options to the ingress trait

[astefanutti]

This PR adds a set of new options to the ingress trait, so it's possible to configure "path-based" Ingress.

As ingresses can traditionally be configured based on annotations, e.g. with the NGINX ingress controller, this PR coincidentally adds support to set trait options of type map from the CLI, e.g.:

$ kamel run \
-t ingress.annotations.'nginx.ingress.kubernetes.io/use-regex'=true \
-t ingress.annotations.'nginx.ingress.kubernetes.io/rewrite-target'='/$2' \
-t ingress.path='/base_path(/|$)(.*)'

Release Note

feat(trait): Add path-based Ingress options to ingress trait
feat(cli): Support setting maps in traits API

Just a reminder, this will go in 2.x, if this is something we want for 1.x, we need to backport on 1.12.x

@oscerd thanks for the reminder. I've created #4090 that targets the release-1.12.x branch, which I assumed is the current 1.x branch.
