Fabric: handle resource tokens (#1667)

* Update contracts for new all resource messages

* Add timestamp to token message signature

* Reconstruct resource tree with databases and collections parsed from token dictionary keys

* Create FabricDatabase and FabricCollection to turn off interaction

* Remove unnecessary FabricCollection derived class

* Handle resource tokens

* Bug fix

* Fix linting issues

* Fix update document

* Fix partitition keys

* Remove special case for FabricDatabase tree node

* Modify readCollections to follow normal flow with Fabric

* Move fabric databases refresh to data access and remove special case in Explorer

* Revert Explorer.tsx changes

* Disable database context menu and delete container context menu

* Remove create database/container button for Fabric

* Fix format

* Renew token logic

* Parallelize read collections calls to speed up

* Disable readDatabaseOffer, because it is too slow for now

* Reduce TOKEN_VALIDITY_MS a bit to make sure renewal happens before expiration. Receving new tokens new refreshes databases

* Add container element for Main app in HTML

* Do not handle "openTab" message anymore

* Fix style of main div

* Simplify conditional load of the fabric .css

* Fix format

* Fix tsc can't find dynamic less import
