Update predefined filters

[DenTray]

As we implemented earlier search filters has predefine postfixes to automatically apply common filters: _from, _to, _in_list, _not_in_list.

We need to modify this list:

1. _gt, _lt postfixes should be added and works as aliases of _from and _to, but apply strict comparison
2. _from and _to postfixes should be deprecated
3. _gte, _lte postfixes should be implemented. They should apply unstrict comparison
