Remove "init_timeout" in RemoteFileClient.get_file

This timeout seems to attempt to retry in the event that the master returns nothing-- but the channel should be responsible for that.

In addition this would retry infinitely since the retry counter was re-initialized on every loop iteration. This meant you spun with an strace that looks something like:

```

Lastly, this retry attempt counter did nothing in the event of 10 failures (assuming it could get one) so it should be safe to remove it all together

Disable zcbuildout tests as they are not running reliably.

These tests are not running reliably, aren't quite testing the functionalty
the way they should, and take too long to run as unit tests. When these get
reinstated, they should be implemented as integration tests instead of unit
tests.

Removed trailing comma from log_granular_levels example; is invalid YAML

Thanks to F. Langelier for the report.
Added note about using log_level_logfile with log_granular_levels
The uninstall operation needs to inherit DPKG_ENV_VARS set above as install and upgrade currently do. Without this packages that prompt on removal cause that state to hang. resolvconf in particular prompts you with a warning about rebooting your system after removal.
