feat(hbase): bypass server for hbase writing (BETA)

[JackyYangPassion]

Mainly check the logic design first without reviewing the code style

1. Support write vertex/edge directly to KV storage
2. Just support customString and customNumber ID now

add a commit to enable CI (need wait after #339 merged)

Nice feature, maybe we need add some ut and usage document later.
