This proposal is a continuation of the POL next steps approved through referendum `#189` (https://hydration.subsquare.io/referenda/189), and if approved, it will:

- withdraw `55%` of the POL `4-Pool` shares from the Omnipool
- withdraw `600,000` `4-Pool` shares from the stablepool, in quantities proportionate to their weight in the pool
- DCA all received native USDT (assetId `10`) into HOLLAR

These steps are laying the groundwork for deprecating the existing `4-Pool` and launching a new `3-Pool` as per referendum `#189`

#196 Withdraw some 4-Pool shares & DCA HOLLAR
