[HELM] Hardcoded Ingress hostnames for main Astronomer components

[CarpathianUA]

Hello,

I wonder why hostnames are hardcoded within Ingress templates? It makes chart absolutely hard to provision without additional DNS sub-zone specifically for Astronomer.

My case:
In our k8s cluster, we already have a prometheus.<baseDomain> as well as a bunch of other similar components, included in the Astronomer Helm chart.
There is no way to overwrite the names:

astronomer/charts/prometheus/templates/_helpers.yaml

Line 50 in f9e8ea7

{{ define "prometheus.url" -}}

astronomer/charts/astronomer/templates/ingress.yaml

Line 38 in f9e8ea7

hosts:

So to be able to bootstrap Astronomer stack under custom domain names we need to provision an additional DNS sub-zone just for Astronomer, so DNS names won't conflict ...

@CarpathianUA Interesting ideas, makes sense. I'd be happy to guide you through submitting a PR if you're interested in adding this feature. I'm not sure it will be prioritized otherwise. I've opened an internal issue so we can discuss and triage it.

@danielhoherd Due to the war between Ukraine and Russia I have very limited availability now (I'm from Ukraine). Would appreciate if you'll prioritize the issue internally - it would greatly increase deployment easiness for your customers.
