Add log filenames and iterate settings.

[alma-socar]

apache2.prototype.logCommand = 'tail -n LINECOUNT /var/log/apache2/access.log | grep \'" [4-5][0-9][0-9] \'';

Currently it only tracks access.log and error.log.
And somehow apache access_log is not sent to slack channel. (Didn't check sending code yet)

How do you mean "add log filenames" ? Make them configureable? Sounds like a good plan.

Regarding access log not sending to channel, it "should" work. It does however only log 4XX and 5XX responses.

1. Yes, configurable due to our setup. We have multiple logs in a single path such as app_access.log, web_access.log and so on.
2. I'll check and comment again.
