#1032 failing upload flag for monitor mgr (#1040)

* 1032 failing upload flag for monitor mgr

* move upload failure fix logic to frontend

* misc corrections

* avoid starting monitor when upload is in progress

* avoid starting monitor when upload is in progress

* prevent monitor side effects on upload (WIP)

* send upload req after notifying mgr

* dispose instead of pause on upld (code not final)

* Revert "dispose instead of pause on upld (code not final)"

This reverts commit 2d5dff2.

* force wait before upload (test)

* always start queued services after uplaod finishes

* test cli with monitor close delay

* clean up unnecessary await(s)

* remove unused dependency

* revert CLI to 0.23

* use master cli for testing, await in upload finish

* remove upload port from pending monitor requests

* fix startQueuedServices

* refinements queued monitors

* clean up monitor mgr state

* fix typo from prev cleanup

* avoid dupl queued monitor services

* variable name changes

* reference latest cli commit in package.json
