Disable circuit breaker for StubAdapter

[kayvonghaffari]

When I run RSpec tests with a lot of failing cases, it causes the circuit breaker to open and many subsequent tests fail with the CircuitbreakerOpen Exception.

We should somehow disable the circuit breaker when the StubAdapter is being used.

We could have something like a Adapter#use_circuit_breaker? method or something 😕. Then client would check if it’s adapter wants to use a circuit breaker or not. That method would return true by default. Then we’d override it in stub adapter to be false.

Alternatively, we could handle this at connection time:

Rester.connect(service, circuit_breaker_enabled: ENV['RACK_ENV'] != 'test')

We could also look at RACK_ENV and RAILS_ENV automatically, and disable it if it's "test".
