Seperate out general poolParams in gamm module

[mattverse]

Currently gamm module is designed in the way that every pool-model being implemented would have their own params struct which would contain exitFee and swapFee.
There's a room to further generalize gamm module by creating a generalized poolParams struct that would contain swapFee and exitFee that all pool models could implement.

I agree with this. Common params scattered around different pool models will make it hard to manage for example swapfee by the governance.

Closing this for now, lets re-consider whats the ideal to do (perhaps in a github discussion), keeping in mind that we want network liveness conditions and volatility to start being able to change swap fee
