Add migration jobs to supported databases

[samuel-lindgren]

The chart currently supports schema initialization for Cassandra and may eventually support it for PostgreSQL . However, neither of them includes automated migration jobs. Adding migration jobs would allow the users to upgrade to newer Cadence versions without manual intervention.

Proposed Changes

• Add migration jobs:
  • Provide a dedicated job for Cassandra migrations.
  • Include a separate job for PostgreSQL migration when/if PostgreSQL is supported.
• Optional enable/disable:
  • Allow users to toggle these jobs in values.yaml based on their deployment preferences.

I will work on this soon.
My idea is this files (supporting all databases and compatible with tls and getting the hosts,passwords and others from values.yaml:

• schema-create-job.yaml (Just create the database, only the first command of cadence-tool)
• schema-setup-job.yaml (Initial 0.0 version of the schema)
• schema-update-job.yaml (Update the schema version to the cadence-server last version)
• schema-elasticsearch-job.yaml (Upload the schema)
