[22/7/20]: [Not setting configuration throws unhelpful exception]

[airlacodes]

Not setting up KarhooConfiguration on the network SDK causes a crash to occur in the Analytics service. Which doesn't necessarily explain why the application crashed.

Furthermore, it would be helpful to set up secrets and keys in a config file that can be read from .gitignore for open source projects using the SDKs. Otherwise by default credentials are exposed unless developers are conscious enough to set up a config file.

Frequency (How often does the bug occur?):
Every time

Expected Behaviour

A more descriptive fatalError such as "missing Karhoo configuration" with instructions on how to fix tit. (Add a configuration in AppDelegate)

Actual Behaviour

What actually happens?
A crash in the analytics service

Screenshots

Reproduction Steps

Steps on how to reproduce?

Attempt to use the KarhooSDK without setting up a configuration.
