Update JenkinsfileWithWaziDeploy with various changes

[fritze2]

The changes in this pipeline have been tested in the SMPO lab environment.

• Switch Build stage from using zAppBuild to zBuilder framework by calling the common backend script zBuilder.sh.
• Add required argument -i ${PackageTarPath} to the common backend scripts wazideploy-generate.sh and wazideploy-deploy.sh.
• Fix broken link on line 5 to https://ibm.github.io/z-devops-acceleration-program/docs/branching/git-branching-model-for-mainframe-dev.
• Change formatting to more easily differentiate between sections for pipeline variables.
• Update pipeline variables sections:
  • Change value of JenkinsAgent to a more generic agent named ZosAgent.
  • Rename pipeverbose to verbose.
  • Rename zAppBuildVerbose to zBuilderVerbose.
  • Add definitions for AppBranch, BuildDir, and Branch. This is in case the user creates a generic pipeline using a single-branch instead of a multi-branch pipeline, so the variables will not be null.
  • Create new variables: DbbCommunityRepo to be configured by the user to point to the installed DBB community repository and DbbPipelineScripts.
  • Change value of WdEnvFileIntegration to point to environment located in the DBB community repository.
  • Create a branchConfig map to replace the series of if conditions that configure branch behavior.
• Allow deployment from branches with "RELEASE" prefix.
• Switch to addSummary DSL from deprecated createSummary DSL.
• Add addWarningBadge and addErrorBadge DSLs on a build issue.
• Wrap DSL calls in dslMethodExists so they don't fail the build.

Hello DBB maintainers, I discovered that there is a similar PR made by Kenny for the IDD Jenkinsfile. I will synchronize my PR with the improvements made in #377 and address the comments Dennis made. I will also break apart the PR into multiple commits to make it easier to review.
