Setting incentive pools subscription and static gas cost

Description

The following proposal configures the minimum IPRPC cost and defines the IPRPC eligible subscriptions. Those are parameters used by Lava's incentive pools. Incentive Pools (or IPRPC, its legacy name) is a program designed to motivate providers to offer services for specific chains using Lava. The pools are funded by DAOs and other contributors. Providers supplying RPC data for IPRPC eligible subscriptions will receive additional rewards from the incentive pool each month. The incentive pools can hold any IBC token. The minimum IPRPC cost serves to discourage users from funding the incentive pools with random, unused coins. This minimum cost acts as an entrance fee for funding the pool. It can also be viewed as a static gas costs in Lava tokens. The proposal will set the minimum IPRPC cost to be 100 LAVA. This means that a fund of X IBC tokens to the incentive pools will cost 100 LAVA to be applied for each month. MagmaDevs currently maintains a Consumer (Gateway) for incentivized chains (IPRPC chains). The Gateway consumer was especially made for the Lava foundation to serve public endpoints. This proposal suggests designating the subscription held by the MagmaDevs Consumer as an IPRPC eligible subscription. If the proposal passes, all providers who serve the MagmaDevs Consumer will receive rewards from the incentive pools.
