Upgrade simapp files to run with latest simd

[andynog]

Change simapp configuration to include more than one connection. This will allow properly testing of queries such as connections per client.

We might need to update the simapp to the latest version in order to have this properly configured. Looks like our current simapp doesn't do client_id validation for a particular connection

Tried to run simd --home ./simapp/ start using a compiled simd built from the latest cosmos-sdk (master) and it spits out an error. I believe it has to do with the proto changes. Our simapp files were generated before protobuf changes on cosmos-sdk. We need to regenerated the simapp folder using the latest simd.

simd --home ./simapp/ start
