OBSV-443 messagebird/pushprom does not respect log-level argument

[sshilko]

The problem

Pushprom 1.0.8 is too verbose on default INFO level.

Trying to use the “documented” -log-level argument for the application does not have effect.

Update from 1.0.7 to 1.0.8 resulting in thousands unnecessary log records polluting the INFO logs.

Definition of Done

Pushprom 1.0.8 does not change behaviour when updating from 1.0.7 for logging.

or Pushprom 1.0.8 default verbosity level changes to “warn” and/or respect the -log-level documented argument.

I will submit the MR with the fix myself :)

Please review #33

Behaviour change:

• UDP listener now listens with timeout of 1 second, inside infinite loop, previously no timeout causes inifinite block.
• HTTP listener write & read-header timeouts of 10 seconds, previously no timeouts
• Log messages are now split between STDERR and STDOUT, previously all "log" messages went to STDERR
• Previously HTTP& UDP servers were never gracefully shutdown, now they react to SIGINT, SIGTERM (no SIGQUIT)
