Hangfire: Provide a ceiling value for `WorkerCount` setting
Every worker owns a connection to a storage. Currently WorkerCount value in BackgroundJobServerOptions is being calculated as a ProcessorCount * 5 value. In usual cases this value is ok as a default, but consider you have a 20-core server. In this case there will be 100 workers, and it is fine. However, since each worker use a connection, this value can produce errors:
- SQL connection pool have 100 connections by default.
- Redis pool have 50 connections by default.
To make things more predictable, the default value should have a maximum at, for example, 40 to produce enough workers and leave some connections for other components.

Hi @odinserj, seems like BackgroundJobServerOptions still allows only a maximum of 20 workers. Is it still required to be max 20, or can it be increased/overridden somehow?

It's a limit only for the default value. You can set as many workers as you want.
