feat(deployment): perform database migrations

[migmartri]

NOTE: This is needed because we've moved to a better database migration mechanism #221 and now the migration process is not automatic in the app but as part of the deployment process.

Updates our Helm Chart to perform database migrations. It's been implemented using helm hooks and kubernetes jobs as suggested here.

I've also seen some Bitnami Charts following the same pattern, so I'll be stick to hooks + jobs instead of init containers for now.

Example of job output for the initial import
