lock is removed even when slack notification times out

edit: see comments for root cause

While testing a freebsd implementation, I noticed slack notifications tended to lag a big.. which caused a timeout. The lock file was removed, despite the failed alert.

Disk usage healthy: /
Lock removed
dial tcp: i/o timeout
Failed to send alert!

The timeout seems to only occur when removing the lock

When replicating the issue on linux, I get the following error.

dial tcp: lookup smtp.domain.localnet on 10.1.30.2:53: no such host

Turns out, I was not passing -s for enabling slack. We should set slack to true if a url is passed, and possible remove the -s flag entirely.
