Use Application Signals wherever possible

[thpierce]

In this commit, we are changing appsignals, app_signals, app_signals, and app signals to applicationsignals, application_signals, application-signals, and application signals wherever possible. Callout aws-application-signals-team was created here: https://github.com/orgs/aws-observability/teams/aws-application-signals-team and has correct permissions on this repo.

Remaining usages:

• aws_opentelemetry_configurator.py - we have to support both old and new config names (e.g. OTEL_AWS_APP_SIGNALS_ENABLED and OTEL_AWS_APPLICATION_SIGNALS_ENABLED)
• application-signals-python-e2e-eks-test.yml, application-signals-python-e2e-ec2-test.yml, appsignals-python-e2e-eks-canary-test.yml, and appsignals-python-e2e-ec2-canary-test.yml - various reasons:
  • We rely on appsignals referenced in other repos that need to be updated first.
  • We emit metrics containing appsignals, which we have alarms on - changing is non-trivial.
  • Workflow names and urls contain appsignals - changing would break links (including runbooks).
  • We are depending on github secrets that are named appsignals
