Add the statistics counter for a number of unprepared statements
executions and expose it with collectd.
Since in our implementation a number of unprepared statements executions
equals to a number of executions of prepare() function we may simply
increment the new statistics counter every time query_processor::get_statement()
is called.
Fixes#1068
