feat(compose): support for setting profiles (testcontainers#738)

# Change

Adds `profiles` support for docker compose.

# Context

I've had to use a workaround in a company project for compose profiles
leading to multiple compose profile files.
This should help by supporting profiles in compose which is a very handy
feature when your service has some variety of ways to run (contextual,
environmental, etc)

Without this, it's still possible to run profiles buy setting the
`COMPOSE_PROFILES` env variable, but this is certainly cleaner and
easier on test writing.
