feat(MM-61865): Add mobile client content load network metrics (#29601)

* MM-61865: Add mobile client content load network metrics

* added new common label

* renaming from MobileClientContentLoad to MobileClientNetworkRequests
* content_load_group => network_request_group

* refactor more NetworkRequest-* changes

* replace contentLoadGroup to networkRequestGroup

* new metrics elapsedTime

* Refactor urlCount to totalRequests

* add averageSpeed metric
* replace contentLoadGroup with networkRequestGroup
* use h.Labels vs commonLabels for network_request_group

* add agent

* add effective latency metrics

* add total parallel requests & total sequential

* mocks generated by mockery

* did a bit of cleanup and sorting

* formatting

* updated the AcceptedNetworkRequestGroups

* cleanup and sorting
