-class sinsp_filter

-call sinsp_filter::push_expression when entering a new nesting level (e.g. parens)
-call sinsp_filter::parse_check to parse a single relational expression
-     parse_check creates a sinsp_filter_check 'chk' of right type for field in this expression
-this 'chk' holds the fieldname, operator, value, and also the boolean op that was "on the left" of the expression (or BO_NONE). Then it is added to the parent sinsp_filter_expression by calling sinsp_filter_expression::add_check

-class sinsp_filter_check // represents single relational expression

-Summary: what we'll need to do:
-
-- add an bool arg `lua_parsing` to sinsp::set_filter(const string& filter) (sinsp.cpp:1285)
-  that bool (defaults false) is passed to the sinsp_filter constructor
-- if true, sinsp_filter constructor will call lua_compile() instead of compile()
-- add a new method sinsp_filter::lua_compile(const string& filter) (filter.cpp)
-  this method calls up into lua with the string and some handle object that lua parser will use.
-
-What lua parser can do with said handle:
-- create a filter_expression
-- create new sinsp_filter_check by calling g_filterlist.new_filter_check_from_fldname (filter.cpp:1483)
-- set its comparison operator and previous bool operator (filter.cpp:1504)
-- parse field name (filter.cpp:1506)
-- parse value (filter.cpp:1610)
