Move Relay-Specific Shared Code to One Place (#1193)

Browse Source 
* add common libs

* asset hubs

* add westend

* bridge hubs

* collectives

* contracts

* emulated tests

* parachain bin

* delete collectives constants and update docs

* integration tests should have apache license (some missing, some needed changing)

* propagate features

* fmt
