let's namespace it

Suggested change

	USE_AZURE_MANAGED_IDENTITY_FOR_DB_AUTH = env(
	"USE_AZURE_MANAGED_IDENTITY_FOR_DB_AUTH", default=False
	)
	USE_AZURE_MANAGED_IDENTITY_FOR_DB_AUTH = env(
	"DJANGO_DB_USE_AZURE_MANAGED_IDENTITY", default=False
	)

Plus, would be cool to signal this via the dsn somehow, e.g.

azuread+postgresql://user@server/database
