Workers

[pbiggar]

Goes most of the way to getting CronChecker and QueueWorker into production, following #3331 and #3267. Also does part of #3272.

This actually disables CronChecker and QueueWorker by commenting them out, as we really don't want two things running here. THere's no services so they won't run anyway, but let's be super sure.

• add cronchecker main code, k8s endpoints, dev servers, and containers
• Split out init code to one per library, in Init.fs
• Make sure all entrypoints are wrapped in Rollbar.lastDitchBlocking
• start to use DARK_CONFIG_TRIGGER_QUEUE_WORKERS

Small fixes:

• new httpclient tests
• fix production for Apiserver and Bwdserver
• fix dotnet wrapper
• fix compile-project for rescript
• use implicit spans in Telemetry, and remove explicit spans. Add comment explaining
