Return service from findCredentials invocation

[rcjpisani]

Issue or RFC Endorsed by Atom's Maintainers

#144

Description of the Change

These changes add the service property to the result of the findCredentials method, introduced by #85.

Alternate Designs

Other alternative solutions would be the use of std::array instead of std::tuple for the definition of Credentials in credentials.h seeing as the values used up until this point are homogenous. I decided to stick with Tuple since it's a generalization of the previously used std::pair. I'm open to tweaking the code as needed, pending review, to highlight any potential issues. C++ is not a language I'm well versed in.

Possible Drawbacks

Possible side effects are a slight increase in memory usage in order to support the return of the service property.

Verification Process

• The program successfully compiled and test suite passed on both Linux (Linux 5.7.8-arch1-1 #1 SMP PREEMPT Thu, 09 Jul 2020 16:34:01 +0000 x86_64 GNU/Linux) and Mac (Darwin 19.5.0 Darwin Kernel Version 19.5.0: Tue May 26 20:41:44 PDT 2020; root:xnu-6153.121.2~2/RELEASE_X86_64 x86_64). Windows testing pending as I do not have access to a working Windows machine.
