currently transformation catalog does not support specification of checksums for executables and containers. proposal is to add checksum support similar to replica catalog format

pegasus: "5.0"
transformations:

• namespace: "diamond"
  name: "preprocess"
  version: "2.0"
  checksum:
  sha256: abc123
  profiles:
  env:
  APP_HOME: "/tmp/myscratch"
  JAVA_HOME: "/opt/java/1.6"
  pegasus:
  clusters.num: "1"
