SUBMARINE-1165. Change Submarine-database from deployment to statefulset
### What is this PR for?
Change the database from deployment to statefulset, so we can avoid some
locking table/database problems when upgrading or restarting database server.
### What type of PR is it?
Refactoring
### Todos
* [x] - Remove database.replicas in CRD. The current database configuration
does not support HA or cluster mode. Delete this configuration to avoid
unnecessary database problems. There are already relevant JIRA issues:
https://issues.apache.org/jira/projects/SUBMARINE/issues/SUBMARINE-1225
* [x] - Replace database resource definition from deployment to statefulset
in submarine-operator
* [x] - we may get nil exception, and we may need to merge PR
https://github.com/apache/submarine/pull/911 before passing git test flow.
### What is the Jira issue?
https://issues.apache.org/jira/projects/SUBMARINE/issues/SUBMARINE-1165
### How should this be tested?
Should be tested by exists cases.
### Screenshots (if appropriate)
No
### Questions:
* Do the license files need updating? No
* Are there breaking changes for older versions? Yes
* Does this need new documentation? No
