[improve]: dab add/update output around config file is noisy and confusing

[JerryNixon]

Current

The output logs are not clear or usable to the developer.

desired dab add

> dab add Jerry --source dbo.table --type table --permissions anonymous:*
Info: Added entity: {entity-name}

Note

Do not include the SUGGESTION output. That's just noise.

Debug experience:

--verbose

> dab add Jerry --source dbo.table --type table --permissions anonymous:*

dbug: Using c:\dev\CD\Demo\dab-config.json
dbug: Source is dbo.TableName
dbug: Type is view

desired dab update

> dab update Jerry --permissions anonymous:*
