fix load test - anvil pods eviction (#1176)

## Motivation

CCIP Load tests were running into failures due to eviction of anvil pods
which was due to cache file outgrowing the ephemeral storage on the pod.

## Solution

Update anvil helm chart
(smartcontractkit/chainlink-testing-framework#1026)
to use a volume for cache storage and use this chart in load tests.
