* Refactor cgroup detection into separate file. We should be able to use the struct in different collectors * Use go routines in perf collector to update Signed-off-by: Mahendra Paipuri <mahendra.paipuri@gmail.com>

* Our first approach of monitoring link level funcs is not going anywhere due to lack of process context in those functions. So we resorted to monitoring TCP and UDP sockets which are more high level but surely we will have correct process context Signed-off-by: Mahendra Paipuri <mahendra.paipuri@gmail.com>

* Make a generic cgroup collector that can be used for different resource managers. Generic cgroup collector wont register itself to Collector interface and it is meant to be used in other collectors. Resource manager collectors must pass a list of valid cgroup paths to cgroup collector for metrics fetching. * Similarly perf collector has been modified to become internal generic collector that must be called from other collectors specific to resource managers. Same goes to ebpf collector where it becomes an internal collector that is meant to be called from other collectors. * cgroup, perf and ebpf collectors take an argument cgroupManager during instantiation that will direct on which processes/cgroups must be monitored. * The side-effect is that we replicate CLI args for each resource manager but this should not be an issue as exporter on a given host will not/should not target two different resource managers. So, operators will never have to deal with duplication. Signed-off-by: Mahendra Paipuri <mahendra.paipuri@gmail.com>
* This will make the Makefile of repo simpler to do everyday development Signed-off-by: Mahendra Paipuri <mahendra.paipuri@gmail.com>
