Print configuration values with yuniql config

[rdagumampan]

To help investigate issues and verify the environment setup, it would be helpful to print configuration values with yuniql config

Print as table just like when you issue yuniql list

yuniql config

Property	Value	Source
Platform	sqlserver	Environment variable
Workspace	c:\temp\yuniql\samples\basic-sample-sqlserver	Environment variable
ConnectionString	Server=localhost,1400;Database=helloyuniql;User Id=SA;Password=P@ssw0rd!	Environment variable
IsDebug	False	Default
IsAutoCreateDatabase	False	Default

Print as json

yuniql config -o json
