AMM_arb balancer's lower gas limit 100000 for approval causing tx delay and submitted twice in Hummingbot #6

Describe the issue Low gas price causing the slow tx approval and subsequent HB order will resubmit another approval request while the previous tx is still in pending state.

Suggestion: Accept fee info for approval endpoint , or submit approval during amm_arb setup for Balancer in Hummingbot.

Humminbot will submit only 1 approval request for token with 0 balance, during the session of the running strategy. Upon investigation, the 2 pending approvals are for 2 different tokens on the arbitrage pair.
