Investigate about multiple environments

[akakshuki]

Is your feature request related to a problem? Please describe.
The project can swap config files or connection strings between environments

Describe the solution you'd like
The project can hide the aspnet setting files or at least use the environments variable to define environments

Ex:
when setting the ASPNET_ENV='development'
The aspnet config file will be set the connection string to

    "DefaultConnection": "Host=localhost:5432;Username=planthor-admin;Password=Planthor@123;Database=PLANTHOR_IDENTITY"

or set ASPNET_ENV='container_development'

   "DefaultConnection": "Host=postgres:5432;Username=planthor-admin;Password=Planthor@123;Database=PLANTHOR_IDENTITY"

and Production configs can be hidden in the Azure key vault
