Start of service level code, which will be tweaked
* stores desired & effective service level
* whenever desired level is changed, effective level will be updated
* allows user to set their desired service level
* allow admin to update desired & effective service level
Merge branch 'develop' into feature/service_level
Add ServiceLevel class to wrap config and give accessors. Has some hacky parts, but seems like okay generic start for now.
Some simplification of code.
We won't want service levels in production mode, and have it so this initial service level code won't break anything if it isn't set in the config.
