Replace Jenkins build, test and static analysis functionality with CodeBuild

[PaulDuvall]

Replace Jenkins build, test and static analysis functionality with AWS CodeBuild. Will need to review the jobs folder to ensure key functionality is replicated.

This should eliminate the need for the following:

• jenkins-instance.json, codepipeline-custom-actions.json
• jobs, configure-jenkins.sh, packer-create-ami.sh
• ...and probably some other files.

It will modify codepipeline-cfn.json and some other files
