Signalling Proposal for OSMO/FIL incentivised pool

This is a signalling proposal to include the FIL pool OSMO/FIL (#1006) into the set of assets that receive OSMO liquidity incentives. After this proposal has passed governance, pool #1006 will be added to the regular incentives program of Osmosis. \n\n## About FIL\nFilecoin is a peer-to-peer network that allows anyone to store and retrieve data on the internet. Built-in economic incentives ensure that files are stored and retrieved reliably and continuously for however long a user specifies. \n\nFilecoin is provided through the Axelar bridge from the Filecoin network. The Filecoin network runs the Filecoin Virtual Machine (FVM), a runtime environment for smart contracts written in Solidity. \n\nWebsite: https://filecoin.io/ \n\n Commonwealth Thread: https://commonwealth.im/osmosis/discussion/11304-filecoin-incentives
