Implement path based setup for all internet facing components

[wiardvanrij]

Currently we use a new ingress subdomain per component. For example:

thanos-querier.some-domain
prometheus.some-domain

It would be easier if we move that towards:
some-domain/thanos-querier
some-domain/promethues

For multiple reasons:

• Users stay on our active domain
• Easier for implementing SSL
