[Bulk-API-Adapter] modify mongoDB configuration to use explicit configs instead of uri

[mdebarros]

Goal:

As a Hub deployers

I want to have each mongoDB client config seperately configurable

so that I can utilise externalised secrets

Acceptance Criteria:

• MongoDB configuration is configrable by seperate configs for host, port, user, database, password
• Each of the MongoDB configuration that is configrable by seperate configs for host, port, user, database, password can be set via environmental variables, and will override any file configs
