Fix tenant deletion on update

Changes proposed in this pull request:

Related to #150

• Add yq package
• Update opensearch job pre-start script to prepare YAML configuration for tenants, roles, and role_mappings for CF orgs so that they are not deleted when securityadmin.sh runs in the post-start script

Things to check

• For any logging statements, is there any chance that they could be logging sensitive data?
• Are log statements using a logging library with a logging level set? Setting a logging level means that log statements "below" that level will not be written to the output. For example, if the logging level is set to INFO and debugging statements are written with log.debug or similar, then they won't be written to the otput, which can prevent unintentional leaks of sensitive data.

Security considerations

We are not adding new permissions or roles, just ensuring that they do not get deleted when the opensearch job restarts
