[sr-dev] db_cassandra - db_cassa_raw_query & INSERT query

[jay binks]

If doing a query that returns no results ( Insert etc )
db_cassa_raw_query would cause these ERRORS to be logged

0(22283) ERROR: db_cassandra [dbcassa_base.cpp:739]: db_cassa_raw_query():
The resultype rows was not set, no point trying to parse result.
0(22283) ERROR: avpops [avpops_db.c:333]: db_query_avp(): cannot do the
query

db_cassa_raw_query would also return -1 as a failure code which caused
avpops_db to log the query failure.

my patch changes the db_cassa_raw_query log message to debug level, and
returns success from the function.

I had a quick look to see if there was an elegant way to determine if we
should expect results, so we can vary the response code based on query
type, but I was unable to find anything other than doing string comparisons
on the query, so I opted to not bother with this as it would be erroneous.

Please find attached patch.

Jay
