Update docker image for more user-friendly usage

[jiacai2050]

Describe This Problem

If new users try ceresdb with docker image, there is no easy way for them to explore data stored in ceresdb.

Proposal

Since ceresdb already support many query protocol, we can include following tools in docker images to help users explore :

• mysql client
• grafana, with ceresdb added as data source by default.

In this way, users can either explore in terminal or web UI.
