Note this PR includes all the additions from #1432 as they're necessary to put the tests in place.
There is really one file of interest for this PR - apps/29-fee/ica_test.go which adds a test similar to transfer_test.go.
The test is a little verbose but essentially follows the flow:

• Create fee enabled interchain accounts channel
• Assert channel ends are both fee enabled
• Escrow a packet fee, assert the pre escrow balance against the post escrow balance
• Fund the interchain account wallet on host chain and build an ICA packet with a basic staking delegation msg
• Relay the packet and assert the account balances after packet fee distribution

Would it be useful to create a helper function in types that creates the default ICA version given the connection IDs?
