[DionJones615]

Changes

Simply passed the lifecycle defined in the Jenkins CRD down to the generated pod definition. The necessary bits appear to already be in the CRD.

ehi @DionJones615 thanks for your contribution.

I think here we miss:

• a guard if lifecycle is empty
• the option listed in the helm chart values and jenkins template

wdyt?
