Add Macos observability lib (#28)

* Add gitignore to node-observ-lib

* Fix typo in node default filteringSelector

* Prep alert group names for macos

* Add macos-observ-lib

* Change overview dashboard:
show networkErrorsAndDroppedPerSec instead of networkErrorPerSec for Linux/MacOS

* Add more alerts

* Move alerts to sep file

* Breaking: Update layout

To allow to locally import linux from macos

* Bring back NodeFilesystemAlmostOutOfFiles alert

* Show only errors when they occur

* Only show network interfaces that had traffic change at least once during selected dashboard interval
