Str-961: Introduce load testing env in fn-tests.

[evgenyzdanovich]

Description

Part of the work related to load testing env. In the follow-ups, the actual load logic is implemented - different types of eth transactions (different eips, deploys, mints, etc)

• Introduce a separate load testing env in fn-tests.
• Create a simple basic_load test against the load testing env that sleeps for some time and the load to reth service is generated in the background
• Currently, the test is disabled, because:
  • logs should be fixed. Currently, there are a lot of debug prints, and it's intended to be used locally.
  • not sure if load tests should be invoked in the CI (maybe periodically?).

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature/Enhancement (non-breaking change which adds functionality or enhances an existing one)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactor
• New or updated tests
• Dependency Update
