Make expunge delete faster for small data sets #7126

Describe the issue
I have suites of integration and system tests that run against HAPI FHIR which involve expunge deleting data in a partition. Prior to version 7 this was a very fast operation, but now it takes several minutes to do what used to be done in seconds. When I look at the job status endpoint I can see that each individual stage takes less than a second to run. So the majority of the time is spent waiting. I believe this is because of the JobMaintenanceServiceImpl having a hardcoded period of 1 minute.
It would be enough for me to be able to configure the period of the JobMaintenanceServiceImpl through the application config that I use through the FHIR jpa-starter project. This setting is already internally configurable for tests.
Alternative solutions are welcome, especially if they just work without configuration.
Environment (please complete the following information):
- HAPI FHIR Version 8.2.0
- OS: [e.g. iOS] ubuntu latest
- Browser [e.g. chrome, safari] java client: ca.uhn.fhir.rest.client.api.GenericClient
