Replace boltdb imports with bbolt import (#5193)
* Replaced. Debugging missing strict dependencies...
* Merge branch 'master' into bbolt-import
* Update import path
* Merge branch 'bbolt-import' of github.com:prysmaticlabs/prysm into bbolt-import
* use forked prombbolt
* Merge branch 'bbolt-import' of github.com:prysmaticlabs/prysm into bbolt-import
* fix
* remove old boltdb reference
* Use correct bolt for pk manager
* Merge branch 'bbolt-import' of github.com:prysmaticlabs/prysm into bbolt-import
* fix for docker build
* gaz, oops
