[ANSIBLE] clever way to construct java classpaths

[DaanHoogland]

when we merge log4j2 the class path and command for the encrypt step becomes

- name: Generate new cm_secretkey_enc
  shell: java -classpath /usr/share/cloudstack-common/lib/cloudstack-utils.jar:/usr/share/cloudstack-common/lib/log4j-api-2.19.0.jar:/usr/share/cloudstack-common/lib/log4j-core-2.19.0.jar com.cloud.utils.crypt.EncryptionCLI -p password -i {{ cm_secretkey }}

this is hard to maintain and the classpath should be constructed from wildcards to be constant over versions.

good finding @DaanHoogland
