[management] Optimize network map updates (#2718)

* Skip peer update on unchanged network map (#2236) * Enhance network updates by skipping unchanged messages Optimizes the network update process by skipping updates where no changes in the peer update message received. * Add unit tests * add locks * Improve concurrency and update peer message handling * Refactor account manager network update tests * fix test * Fix inverted network map update condition * Add default group and policy to test data * Run peer updates in a separate goroutine * Refactor * Refactor lock * Fix peers update by including NetworkMap and posture Checks * go mod tidy * fix merge Signed-off-by: bcmmbaga <bethuelmbaga12@gmail.com> * fix merge Signed-off-by: bcmmbaga <bethuelmbaga12@gmail.com> * [management] Skip account peers update if no changes affect peers (#2310) * Remove incrementing network serial and updating peers after group deletion * Update account peer if posture check is linked to policy * Remove account peers update on saving setup key * Refactor group link checking into re-usable functions * Add HasPeers function to group * Refactor group management * Optimize group change effects on account peers * Update account peers if ns group has peers * Refactor group changes * Optimize account peers update in DNS settings * Optimize update of account peers on jwt groups sync * Refactor peer account updates for efficiency * Optimize peer update on user deletion and changes * Remove condition check for network serial update * Optimize account peers updates on route changes * Remove UpdatePeerSSHKey method * Remove unused isPolicyRuleGroupsEmpty * Add tests for peer update behavior on posture check changes * Add tests for peer update behavior on policy changes * Add tests for peer update behavior on group changes * Add tests for peer update behavior on dns settings changes * Refactor * Add tests for peer update behavior on name server changes * Add tests for peer update behavior on user changes * Add tests for peer update behavior on route changes * fix tests * Add tests for peer update behavior on setup key changes * Add tests for peer update behavior on peers changes * fix merge * Fix tests * go mod tidy * Add NameServer and Route comparators * Update network map diff logic with custom comparators * Add tests * Refactor duplicate diff handling logic * fix linter * fix tests * Refactor policy group handling and update logic.
