  cachedb_redis: Allow quoting strings in raw queries

In case the Redis raw query string arguments include whitespace (' ',
\t, \r, \n), script developers can now enclose them in single (') or
double quotes ("), and OpenSIPS will pass the correct string to Redis.

For example:
    cache_raw_query("redis", "SET foo \"bar baz\"", "$avp(result)");
        or:
    cache_raw_query("redis", "SET foo 'bar baz'", "$avp(result)");

... are now possible and equivalent.  Both of these will set the
"bar baz" value, without the quotes.

NEW module parameter in order to maintain backwards-compatibility with
previous code (default: 0):

    modparam("cachedb_redis", "enable_query_arg_quoting", 1)

Fixes #2036
