Reduce the default value of maximum upstream connections on the DNS
proxy to guarantee it works on single-core and other low-end hardware.
Further testing could allow for a safe increase of this value.
Allows defining a limit to the number of connections that can be
established with the upstream DNS host.
If left unset, there may be situations where connections fail to
establish, which causes the Transport to create an influx of connections
causing upstream to throttle our requests and triggering a runaway
effect resulting in high CPU usage. See https://github.com/cloudflare/cloudflared/issues/91
Tunnel delete is successful even if we don't find the credentials
file in the user's filesystem. We no longer "error" indicating this
is a problem. This fix also enables chaining of the delete command
by removing a pre-mature return if the credentials file is not found.
dpkg does not support bzip2 compression, so fails to unpack and install
the built package. By omitting the option, fpm defaults to gzip which is
the default supported option by dpkg.

This removes the redundant chgrp command from the publish step when
pushing packages to our public repositories. The directory being pushed
to has the setgid bit set on it, which means that we don't need to force
the group using this command. Further, attempting to do so resulted in
an error as the cfsync user does not have the appropriate permissions to
use the chgrp command.
This updates the public repository upload process to change the group on
the uploaded files to `cf` and adds the write permission for members of
the group. This should allow the `cf` user to properly overwrite the
file when signing it.
