[Feat]: Ability to customize service name per container/port

What feature?

I'd like to have the ability to rename/customize the service name that is given to a particular container/port combination.

For example a docker-compose file like this:

services:
  service-a:
    ports:
    - 8080:8080
    - 8081:8081

Gives two urls:

https://service-a-ui-8080-<branch>-<random>.livecycle.run/
https://service-a-ui-8081-<branch>-<random>.livecycle.run/

I'd like the ability to override the urls to anything I would like: i.e.

# for service-a 8080
https://api-<branch>-<random>.livecycle.run/

# for service-a 8081
https://metrics-<branch>-<random>.livecycle.run/

Ideally, this would still work with the service discovery and PREEVY_BASE_URL documented here

Describe the solution you'd like

The existing preevy.expose label could be augmented to support an optional prefix of name=

Example:

preevy.expose: api=8080,metrics=8081

The only downside I can think of is if you might have multiple containers that would define a specific url, and this would have to be caught and have an error thrown (i.e. if two containers specified an api port to expose). This is an example of an invalid config:

services:
  service-a:
    ports:
    - 8080:8080
    labels:
      preevy.expose: api=8080
  service-b:
    ports:
    - 7777:7777
    labels:
      # both containers use api, this would be invalid
      preevy.expose: api=7777

Describe alternatives you've considered

Currently the only way I can think of doing this is to rename my containers
