Description:
add boltdb implement for db interface.
The boltdb is safe and high performence embedded KV database. It is based on B+tree and Mmap.
Now it is maintained by etcd-io org. https://github.com/etcd-io/bbolt
It is much better than LSM tree (levelDB) when RANDOM and SCAN read.
Replaced #3604
Refs #1835
Commits:
* add boltdb for storage
* update boltdb in gopkg.toml
* update bbolt in Gopkg.lock
* dep update Gopkg.lock
* add boltdb'bucket when create Boltdb
* some modifies
* address my own comments
* fix most of the Iterator tests for boltdb
* bolt does not support concurrent writes while iterating
* add WARNING word
* note that ReadOnly option is not supported
* fixes after Ismail's review
