POS-2399: ganache bug workaround to reduce smoke_test time in CI

[marcello33]

Description

Often, the checkpoints submission during the e2e tests in the CI takes a very long time (35+ mins) due to lack of funds in ganache accounts (with index > 0), which ends up in checkpoints submission failure, and subsequent rotation until it's accounts[0] turn.
This PR introduces a new script to fund the ganache accounts right before the e2e tests, to reduce the checkpoint submission time from 35+ mins to around 2 mins.
