[Improvement] feedback from Sealos

• The service crashed when the Pg connection number and QPS were high.
• The cluster status and pod status are inconsistent. clusters can terminate faster than pods.
• The minimum value of storage. It is easy to crash if it is too small, and it is troublesome for multi-tenant services if it is too large.
• A unified change operation that can modify multiple parameter values at once is needed. Currently, we achieve this by modifying the YAML file.
• There is a quota problem, no default resource limits are set for containers such as metrics.
• Don't want the database to allow login without a password.
• There are restrictions on the database specifications which we hope to remove.
• PVC usage cannot be viewed.

There are too few logs, which makes troubleshooting difficult. For this, could you please describe in detail which logs are required. @sakcer
