Simplify aspnet logging

[tnotheis]

Readiness checklist

• I added/updated unit tests.
• I added/updated integration tests.
• I ensured that the PR title is good enough for the changelog.
• I labeled the PR.

This PR includes the following:

• It mainly reduces the noise of ASP.NET Core default logs by reducing the log level to Warning and at the same time adding the SerilogRequestLogging middleware, which summarizes each request.
• I also added "Seq" for local development. Seq is a tool to view structured logs. I added it as a container to the docker-compose stack, so you can now access the logs on locahost:8081.
• I also increased the default log level from Error to Warning, while overriding the default log level for our backbone internal logs to Information
• Finally, I surrounded the startup logic with a try catch block, and added some log statements to catch and finally, as this seems to be best practice.
