[Enhancement]: Add param to extend the timeout on startup

[wildum]

Proposal

In my tests the LGTM test containers stack times out because it sometimes takes slightly more than a minute to be ready, and the default timeout for wait.ForLog is 60s.

WaitingFor: wait.ForLog(".*The OpenTelemetry collector and the Grafana LGTM stack are up and running.*\\s").AsRegexp().WithOccurrence(1),

It would be nice to have the possibility to set WithStartupTimeout to it or at least of a bigger default

@wildum sorry for the late response 🙏 You could use add testcontainers.WithWaitStrategy which would override the module strategies. We also have testcontainers.WithAdditionalWaitStrategy which appends, so we cover both use cases: users wanting to replace, or to append.
