* Redis 3.2 basic new config support

getvar_emptystring is a clone of getvar from stdlib with the only
difference, that it returns an empty string instead of undef. But
getvar_emptystring is always used with pick which handles empty strings and
undef the same way. So there is no need at the moment for getvar_emptystring
and even if there is a need in the future it would be better to use something
like:

(getvar('dummy') == undef) ? { true: '', default: getvar('dummy') }

The reason is that since the copying of the getvar function to
getvar_emptystring the getvar function was updated to not send warnings
regarding undefined variables, but this update was never adopted into the
getvar_emptystring function. And thats the cause for issue #227

* Allows running of redis-cli commands via tasks
* `/opt/puppetlabs/puppet/bin/bolt task run redis::redis_cli --modules /etc/puppetlabs/code/modules/ --nodes localhost --user root --password root command=ping`

* Allows cleaner test setup

* Debian Stretch also added a separate package 
also: https://packages.debian.org/stretch/redis-sentinel
* Closes #253

* This commit updates the mode for redis run directory on Debian platforms without systemd. * Without this change puppet will attempt to change the mode and group on /var/run/redis during every puppet run, which triggers a refresh.
