Allow for a preconfigured number of Tendermint node failures #43
Description
We have a long-term requirement coming from GoT where experiments will need to be conducted under load where some nodes might fail. At present, the default behaviour of tm-load-test is to fail the entire load test completely.
We need tm-load-test to:
- be configurable in the number of Tendermint node failures it can tolerate, and
- have the ability to keep retrying to connect to failed Tendermint node endpoints.
This functionality needs to apply to both master/slave mode and standalone mode.
