Review comment:
question 2 of 2: If (and that is an if) the circuit breaker manager no
longer needs to be configurable then perhaps the ` PluginInfoInitialized` no
longer needs to be implemented here?

question 1 of 2: If circuit breakers are individually pluggable, is
there still a requirement for the circuit breaker manager to be configurable
too?

In addition, it is a good practice to exponentially back off while retrying

+== Adding New Circuit Breakers
+To add new circuit breakers, add the new circuit breaker's class and required
parameters:
+
+[source,xml]
+----
+<circuitBreaker class="foobar" enabled="true">
+ <bool name="enabled">true</bool>
+ <int name="threshold">75</int>
+</circuitBreaker>
Review comment:
```suggestion
<circuitBreaker class="foobar" enabled="true">
<int name="threshold">75</int>
</circuitBreaker>
```
I wonder if the `enabled` flag could be removed in favour of the `enabled`
attribute?
