New CUSTOM log level in integrator for developer logs Merged

Right now, a developer can use the existing log levels to write out custom logs using LOG.info(), .warn() etc.

These log levels are also used for system generated logs as well.

A lot of Integrator developers use the LOG.warn() type log message to write out critical information in a groovy job, or some other process. It is very helpful as it is coloured yellow and highlights the message against the green info logs and so it is easy to find.

The problem with using this warn log type, is that the job will complete with 'warnings' (even if there are no warnings/errors apart from these custom messages).

It would be useful to have a log type that is purely just for the developer, and colour coded so it stands out in the log. If used, it would have no impact on the job status.
