Prop 494: Enable Superfluid Staking on IST/OSMO & BLD/OSMO

On passing, this proposal would enable Superfluid Staking on the OSMO/BLD (#795) pool and OSMO/IST (#837) pool on Osmosis.

## Details
Superfluid proposals ask whether governance trusts in the stability and security of the chain sufficiently to allow their tokens to have an influence on Osmosis governance.

This proposal would enable Superfluid Staking in the OSMO/BLD (#795) pool and OSMO/IST (#837) pool.

If enabled at the current 50% discount rate, an additional ~705 thousand OSMO can be used to secure the network through staking.
