Unify redis interaction in a class
* allow passing partial config via new()
config will be merged using defined defaults so
missing keys will be appended using values from defaults

We are going to use both modules app_lua and app_lua_sr until we
solve the missing pieces on KEMI:
* KSR.pvx.xavp_get() returns a string like '<<xavp:%p>>' not a table like
sr.xavp.get()
* KEMI lacks of something like sr.xavp.get_keys() funtion
So, migrate everything that we can to KEMI and keep using sr approach
for just that two cases
- mocks/sr.lua: use same objects for same behaviour
