handle database charset/collation changes

[jycor]

This PR makes dolt aware of database collation changes. We treat database collation changes similarly to a collation change to a table.

To properly show a dolt diff we need to add support for show create database as of ..., which would require changes to vitess and gms. For now, we just show the new create statement. Addtionally, we should add support to resolve database collation merge conflicts.

Affected functions are:

• dolt add
• dolt commit
• dolt status
• dolt diff
• dolt merge
