Fix function calls with inconsistent argument breaking

[pleshakov]

Proposed changes

Problem:

• The code doesn't follow the guideline: when breaking up a call, choose to break after each parameter argument. See https://github.com/nginxinc/nginx-kubernetes-gateway/blob/0ff13226b16cfec44f509542b25bc3f2fcf610cc/docs/developer/go-style-guide.md#consistent-line-breaks
• THe guidelines don't have an example of a function call

Solution:

• Fix the problems in the code, except for ginkgo helpers in tests, because of their readability.
• Add an example of a functional call to the guidelines

Testing: N/A

Closes N/A

Note: this was promised in the PR review -- #905 (comment)
