Refactor Functions to Improve Readability

[renaz6]

Refactor long functions

There are a few long functions that should be refactored and broken up into more readable sections.
By default, the funlen linter has a limit of 60 lines or 40 statements per function. It is the goal to adhere to these standards.
Currently, the funlen linter in this repo is disabled, this should be enabled as part of this issue. It can be enabled by adding it to the enable section of the .golanci.yaml config file.

To Do

• Enable funlen linter in the .golanci.yaml config file
• Run the linter golangci-lint run
• Refactor and break up the functions the linter complains about

Update deprecated libraries

The staticcheck linter checks for deprecated imports. This has been disabled for imports of webpa-common/v2/logging, but should be enabled as part of this ticket. A new logger will need to be added.

To Do

• Search for nolint:staticcheck in the repo and remove the comments
• Run the linter golangci-lint run
• Reconfigure logging in those files, most likely using uber/zap
