JenkinsMaster container configuration does not receive Lifecycle configuration set in CRD

[DionJones615]

Describe the bug When setting a Lifecycle configuration for the JenkinsMaster container in the Jenkins CRD, it does not have any effect.

To Reproduce

1. Set a Lifecycle configuration for the JenkinsMaster container such as:

   [...]
   spec:
   master:
   containers:
   - name: jenkins-master
     lifecycle:
       preStop:
         exec:
           command:
             - "/bin/bash"
             - "-c"
             - |-
               _log() {
                   local level="$1"
                   local message="$2"
                   local timestamp=$(date '+%Y-%m-%d %H:%M:%S')
                   if [[ "$level" =~ ^(ERROR|ERR|error|err)$ ]]; then
                       echo "${timestamp} - ${level} - ${message}" > /proc/1/fd/2
                   fi
                   echo "${timestamp} - ${level} - ${message}" > /proc/1/fd/1
               }
   
               NAMESPACE=$(cat /var/run/secrets/kubernetes.io/serviceaccount/namespace)
               TOKEN=$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)
               CACERT=/var/run/secrets/kubernetes.io/serviceaccount/ca.crt
   
               while [[ ! "$(curl -s --cacert ${CACERT} --header "Authorization: Bearer ${TOKEN}" -X GET https://${KUBERNETES_SERVICE_HOST}:${KUBERNETES_PORT_443_TCP_PORT}/api/v1/namespaces/$NAMESPACE/pods/$HOSTNAME | sed -n '/"name": "backup"/,/}/p' | grep terminated)" ]]; do
                   _log "INFO" "[preStop] Waiting for backup container to terminate..."
                   sleep 5
               }
   [...]

2. Observe that the resulting Jenkins pod configuration does not include this lifecycle configuration

Additional information

It appears that the Lifecycle is not passed to the container config here. However, I suspect reconciliation probably needs an update as well

Jenkins Operator version: 0.8.0

Yep indeed is not passed, do you mind create a PR? it should be easy, we just need the changes in pod.go (with handling of default empty) and helm chart values/template.
