Address S104: Files should not have too many lines of code

[bart-vmware]

Address existing violations of S104: Files should not have too many lines of code in the codebase and set severity to Warning in Steeltoe.Debug.ruleset and Steeltoe.Release.ruleset.

To find existing violations, enable the rule (see above) and rebuild src/Steeltoe.All.sln to make them appear in the Output window.

To address the violations, choose from the following on a case-by-case basis:

• Fix the violation by splitting the code over multiple files (use partial classes if needed)
• ~Suppress the violation in code using #pragma warning disable/restore, preceded by a justification comment if not obvious~
