Remove unused dependencies

[Celebrate-future]

@fjolin-intuit Hi, I am a user of project com.intuit.quickbooks-online:ipp-v3-java-devkit:6.1.1. I found that its pom file introduced 53 dependencies. However, among them, 12 libraries (22%) have not been used by your project (the redundant dependencies are listed below). This PR helps com.intuit.quickbooks-online:ipp-v3-java-devkit:6.1.1 lose weight :) I have tested the revised configuration in my local environment. It is safe to remove the unused libraries.

Best regards
