[Feature] : Differentiate real server exception(5xx) vs client exceptions(4xx)

[sriharsha2587]

Is your feature request related to a problem? Please describe.

Unable to know with the response in failover library whether its a real server exception or a client exception

Describe the solution you'd like

It would be nice to parameterize the exceptions that failover library can consider like 5xx exceptions and exclude others. May be dependes on the consumers of the library to choose what exceptions they want to handle as part of failover.

Describe alternatives you've considered

As a tactical, we can also provide a status code of the exception in the response so that client can decide what they want to do with a specific exception.

Which module is impacted

The impacted modules are :

• failover-domain
• [x ] failover-core
• failover-store-inmemory
