[P1BIGROCKS-1838](https://jira.il2.dso.mil/browse/P1BIGROCKS-1838) Build one or more library charts to allow better re-use throughout Big Bang packages and product. Some initial thoughts are: * [ ] image pull secret creation/checking * [ ] Need to get input from Shanks on additional templates and library charts. Library chart _can_ be hosted and referenced as an OCI artifact _for now_, until we (p1) decide a better strategy around helm chart distribution.
