Beginning of Bloop integration (#595)

* Sync with latest versions, started bloop connection

* BloopModule back to the bare minimum

* Added first Bloop related unit-tests

* More tests

* Fixed global module usage.

* Added resolution in bloop config

* More tests, using correct repository list

* revert dev change

* Changed moduleSourceMap implementation

* Using path-dependant trait for the module

This facilitates testing by preventing the trait from referencing
a global module.

* Added semanticDB to bloopConfig

* Added documentation

* Install returns pathRefs instead of paths

* bumped semanticDB

* Better use of mill's cache, avoid duplication of work

* addressing comments
