Add Success level about monolog

[Seldaek]

Generally logs are there to look at when things went wrong, that's why the main focus is always on errors. Typically normal operation stuff like success can just be logged at the INFO level. I don't think adding a level is gonna help, there are already too many I would say and since they're sequential you would at best add one between INFO and NOTICE, which would not be much use I think.

Another strategy is to create two loggers with different handlers, one that you use to log specific success messages and the other for errors. Then you can route the messages differently.

Probably You are right, as my intention was to use monolog for collecting statistics about certain events, rather than just logging them.

As I've learnt from you, statsd would be a better solution for stats collecting and machine analyzing,
while logs are actually meant for human reading.

My implementation would be adding another, custom, handler for monolog, that will capture the log stuff and send it to stats aggregating system based on some context data that I'll pass along with the 'log' message itself.

Thanks.
