TimescaleDB: Add DB migration scripts from v1 to v2 schema environment

[Nana-EC]

Problem
The cleanest way to move from v1 to v2 would be to migrate the v1 database into a new v2 database.
As such users would need a migration process/script to simplify the process

Solution

• Provide migration scripts to move from v1 to v2 environment locally and across providers
• Provide init script that creates necessary users

Alternatives

Additional Context

• Should support cloud sql to Kubernetes env, but could also be local Postgres to local Postgres
