Extend management to sync meta and posture checks with peer (#1727)

* Add method to retrieve peer's applied posture checks

* Add posture checks in server response and update proto messages

* Refactor

* Extends peer metadata synchronization through SyncRequest and propagate posture changes on syncResponse

* Remove account lock

* Pass system info on sync

* Fix tests

* Refactor

* resolve merge

* Evaluate process check on client (#1749)

* implement  server and client sync peer meta alongside mocks

* wip: add check file and process

* Add files to peer metadata for process check

* wip: update peer meta on first sync

* Add files to peer's metadata

* Evaluate process check using files from peer metadata

* Fix panic and append windows path to files

* Fix check network address and files equality

* Evaluate active process on darwin

* Evaluate active process on linux

* Skip processing processes if no paths are set

* Return network map on peer meta-sync and update account peer's

* Update client network map on meta sync

* Get system info with applied checks

* Add windows package

* Remove a network map from sync meta-response

* Update checks proto message

* Keep client checks state and sync meta on checks change

* Evaluate a running process

* skip build for android and ios

* skip check file and process for android and ios

* bump gopsutil version

* fix tests

* move process check to separate os file

* refactor

* evaluate info with checks on receiving management events

* skip meta-update for an old client with no meta-sync support

* Check if peer meta is empty without reflection
