Add an option to stop the application from spring-boot-properties-migrator

[ttddyy]

When spring-boot-properties-migrator detects an error (and/or warning) report, it would be nice to have an option to prevent the application from starting up.

I would like to enforce the proper usage of properties in the application (avoiding the use of deprecated or removed properties). Logs are easily buried, and developers often do not pay attention during development.
It would be beneficial to fail fast to detect incorrect usage of properties rather than discovering it the hard way later on.
