control: move segments and trust endpoints to separate packages

Move `/segment*`, `/trc*` and `/certificate*` endpoints to separate package so they can easily be added to other services.
 - Moved segments  and trust endpoints from `control/spec.yml` to `segments/spec.yml` and `cppki/spec.yml` respectively.
 - Moved implementations and tests of segments and trust endpoints to separate package.
 - Updated instantiations of the api servers in the respective `main.go` files.
