Improve current implementation of shared_buffers value calculation

the concept is:

check if pg_stat_statements is installed. if not, use default formula
implement job (inherited from JobBase) to log statistic values from pg_stat_statements view
calculate value {shared_blks_hit / shared_blks_read} for each statement and get average
use retrieved average during calculation:
if cache is relatively (?) low and shared_buffers doesn't occupy more then 30% (?) of total server RAM, suggest higher value
