LokistackSchema should be automatically upgraded on operator upgrade as per the latest schema available.

Manually keeping a trace of the dates of the schema change is difficult. It would be helpful if these fields are configured automatically by the operator.

    schemas:
    - effectiveDate: "2022-06-01"
      version: v12
    - effectiveDate: "2024-04-02"
      version: v13
--- OUTPUT OMMITED --- 

As of now it is manually needed to add a new entry with version set to v13 and an effective date in the future. For example: If the schema upgrade is implemented on 2024-04-01, then effective date should be set to 2024-04-02. Also need to keep a trace of dates of older achema change.
