This patch makes it so detaching and reattaching programs is no longer needed for updating the list of monitored paths. This is achieved by first loading all the new paths into the BPF trie map and then removing the entries that are not part of the new configuration. An integration test was added to ensure adding new paths does not remove existing paths accidentally.

* ROX-30836: implement hotreloading for monitored paths This patch implements hotreloading for the monitored paths. In order to achieve this, the BPF worker will need to detach all LSM hooks before messing with the prefix path map in order to prevent any problems that may arise of events happening in undefined states. This is achieved by keeping a list of links for the programs and dropping them, then re-filling the list once the programs are re-attached. The path prefix map is cleared by keeping a copy of the list of paths that are being monitored, then the new list is added in and a copy of it is stored. * Add test for monitored paths hotreloading * Reduce code duplication on BPF programs handling * Minor cleanup * feat(hot-reload): reload paths on the fly (#128) This patch makes it so detaching and reattaching programs is no longer needed for updating the list of monitored paths.
