[performance] cached oauth database types (#2838)

* update token + client code to use struct caches

* add code comments

* slight tweak to default mem ratios

* fix envparsing

* add appropriate invalidate hooks

* update the tokenstore sweeping function to rely on caches

* update to use PutClient()

* add ClientID to list of token struct indices
