Improve application role testability
Remove different phases for application role as those are supposed to run after each other anyway from playbook and pre/post steps can be disabled by other means. Enable Helm override file generation customization by delegating it to separate role. Separate Helm file transfer to own module. NOTE: install.yml with all Helm commands (shell/command) is not idempotent and should be fixed with separate commit. Issue-ID: OOM-1655 Change-Id: Ib29773c4d64a0529c71c3f93c2af7265ae94059f Signed-off-by: Samuli Silvius <s.silvius@partner.samsung.com>
