Make default value options work like mysql

[ygf11]

Describe This Problem

Support default value for columns in Ceresdb.

Proposal

In #249, we want to implement the base feature of Default value option for columns.

The next work is to make normal expr works, just allow expr to reference other columns.

As @jiacai2050 suggest, mysql only allow to reference a column defined before it, so we can do like mysql do, and support other complex feature in the future.
