[FEATURE] Un-hardcode the no-ssl configuration to allow external postgres databases

[gilbahat]

Feature Description

Un-hardcode the no-ssl configuration to allow external postgres databases (line 49, internal/common/db.go)

Reason for Need

Hardcoding a no-ssl configuration prevents using an external postgres with ssl. such a configuration may be desired e.g. when using cloud-hosted instances.

Proposed Solution

1. Remove the hardcode and make it configurable into an environment variable.
2. Alternatively, respect the PGSSLMODE environment variable by the standard postgres client

Alternatives

If there are alternative ways to address this issue, please describe them.
