Remove deprecated Pool/Share statistic models. The information is stored in

Change various IntegerFeilds to BigIntegerFields in smart manager that can be
larger than 2TB.
Add custom postgresql.conf file to fix the reboot bug.
Separate postgres setup and conf in buildout
preserve permissions when editing hosts file.
