Following on from approval of referendum `#255` (https://hydration.subsquare.io/referenda/255) - this whitelisted proposal will, if approved:

- removes all DOT LPs from farms (`987`)
- removes all DOT LPs from Omnipool (`1354`)
- migrates Polkadot Treasury LP to aDOT LP
- sets existing DCA schedules with functioning route
- removes DOT from Omnipool as tradable token - *users can still trade DOT as currently due to the presence of aDOT in Omnipool - this is NOT removal of the DOT token from Hydration*

This one is a monster, executed as a batch of three whitelisted calls - each whitelisting a schedule. In total this referendum will be executed over `165` blocks. It is structured in this way due to the sheer size of the call.

#257 Remove DOT from Omnipool
