update redis to use map.jinja and able to install redis on centos/redhat based systems
redis now installs and gets the map.jinja values and probably the overrides from pillar.get - redis.server is broken as checking if I can inherit variables from e.g. common or init.sls
remove files that are actually templates but keep files dir just in case
server installs and variables from map.jinja currently overwrite template vars from pillars - needs fixing
Fixing server.sls, updating pillar.example, remove bind from map.jinja as was only for testing, update template for 2.4 config to use correct variable names and how it's meant to be done to get the values from either map.jinja or pillar.
