4a73ef8824 When overriding rules, ensure that the sources match 
In places where a second rule definition might replace, append to, or
replace items from a base rule, ensure that the source of the second
rule definiton matches the first.

This already existed for defines, but for other changes. There was a
bug where a second definition might exist for a different source, but
the additional rule was used anyway.

This now returns the same error for these other changes e.g. "Rule has
been re-defined..." as define.

a44b311333 Add a source to rule_update_info 
It's possible that someone might want to override a property for a
non-syscall rule source. To assist in this, decode any source property
for rules with append/override and save it in the rule_update_info
object. For the source property only, the value for source can be
empty e.g. 'source: ' or an empty string e.g. 'source: ""'. Both of
those are considered valid but result in an empty source.

A later change will ensure that the sources match up when
appending/redefining/overriding/enabling.

5f13a9be08 Add equality operators for indexed_vector/falco_{list,macro,rule} 
Add an equality operator for indexed_vector.

As indexed_vectors commonly hold falco lists/macros/rules, also add
equality operators for those structs. For condition/sinsp_filter
shared_ptrs, the operator checks that the shared_ptrs point to the
same underlying memory.

3a6d1c8c5d feat(stats): add host_netinfo networking information stats family 
Introduce host_netinfo stats family to hold information regarding host
networking. At the moment, it only provides ipv4 and ipv6 addresses
list for each interface available on the host. The naming schema for
the introduced stats is
falco.host_netinfo.interfaces.<ifname>.protocols.<ipv4|ipv6>.addresses.

5ba94a36bd fix(falco_metrics): remove ifinfo_json stat/metric 
Using JSON as value prevents any meaningful aggregation for the stats.
Splitting these information into multiple labels can drastically
increase the number of dimensions, as the number of interfaces and
addresses can be high in some environment. Moreover, these information
are not currently refreshed, even if they can frequently change. Given
these reasons, remove ifinfo_json from stats and metrics.
