Reduce time spent in CI

Summary

Test	Time taken	Action
test_atomic_ibc_forward_hop_transfer	> 720s	Reduce time
test_misspelled_memo_content_ibc_forward_transfer	> 420s	Reduce time
test_misspelled_memo_fields_ibc_forward_transfer	> 420s	Reduce time
test_filter_incentivized_fees_relayer	> 300s	Reduce time
test_pay_packet_fee_async	> 300s	Reduce time
test_ternary_ibc_transfer	> 420s	Reduce time
python_end_to_end_tests	> 240s	Remove test

Total time: 47min (2'820s)

If we can get all of those under 120s we'd save ~35min (2'100s)

Here are some thoughts on the mentioned tests, let me know what you think.

Tests with more than 2 chains

The time for these tests is mostly due to the Connection and Channel handshakes:

• test_atomic_ibc_forward_hop_transfer need 4 chains to run, as it will test forwarding a packet from A to D, passing by B and C. The bootstrapping will fully connect chains A, B, C and D
• test_misspelled_memo_content_ibc_forward_transfer and test_misspelled_memo_fields_ibc_forward_transfer bootstrap chains A, B and C
• test_ternary_ibc_transfer bootstraps chains A, B and C

For this reducing the handshake times should decrease the run time of all tests.

ICS29 tests

• test_filter_incentivized_fees_relayer
• test_pay_packet_fee_async

Some ICS29 tests take longer due to a change introduced in v8.1.0+, where only the highest value between recv+ack and timeout fee is escrowed. First verifies if the max(recv+ack, timeout) is escrowed and if it fails after 90 seconds, verifies if recv+ack+timeout is escrowed. This allows the test to be compatible with both implementation.

For this solution we could either verify if the amount a or b is escrowed at each iteration, or add a feature flag to determine if the chain is running v8.1.0+ or not.

CLI tests

The python_end_to_end_tests is testing many CLIs. This takes a long time as it contains many tests grouped in a single one.
Not sure if there is any way to easily reduce the time for this one, but it might be a good idea to migrate the tests to use the test framework so that we can remove the python dependency.
