Added syslog alerter

[monwolf]

I would like to contribute to your project with my basic syslog alerter.

I don't understand why not passing the test.

[Qmando]

The test failure is unrelated to your code changes. A new version of pytest or some dev dependency caused the failures. It's now been fixed in master.

Would be nice to get this one merged. What needs to be done?

[Qmando]

This can probably be merged. I'll take a look at it again.

In the meantime, you could try using command alerter + logger.

alert:
- command
command: ["/usr/bin/logger", "-t", "elastalert"]
pipe_match_json: true

@Qmando Great news! Thanks for the suggestion, I'm using logger currently, but I haven't figured out a way to spoof hostname in the syslog message field. I would like to be able to rewrite what I want in that.

@Qmando any update on this?
