Title: ENG-7341: Eliminate confusion and a possible race condition in

retrieving the current deployment config:
- Add the deploymentBytes to CatalogContext. Use them instead of ZK
where appropriate (anything other than initial deployment file read or
@UpdateApplicationCatalog).
- Remove m_deployment from RealVoltDB, replace with the deployment from
the current CatalogContext.
- Have CatalogContext generate the SHA-1 hash for the deployment bytes
rather than expecting the hash to be provided along with the bytes on
construction or update.
