[locust] Adjust worker and contract balances

[aborg-dev]

This addresses two problems:

• The initial balance of master funding account was not enough for 16 workers, so decreasing it 10x (still 10x higher than the previous value)
• Decrease the starting balance of individual user accounts - this is possible now as in FT benchmark, we disable gas price changes during congestion
