Sync default properties with upstream (#86)

Removed some defaults to be closer to upstream configuration

CHE_PREDEFINED_STACKS_RELOAD__ON__START - not used in Che 7
CHE_WORKSPACE_AUTO_START - wrong parameter, has to be CHE_WORKSPACE_AUTO__START, upstream default value - true
CHE_INFRA_KUBERNETES_WORKSPACE__UNRECOVERABLE__EVENTS - upstream value FailedMount,FailedScheduling,MountVolume.SetUp failed,Failed to pull image,FailedCreate
CHE_LIMITS_WORKSPACE_IDLE_TIMEOUT - upstream value 1800000
CHE_INFRA_KUBERNETES_SERVICE__ACCOUNT__NAME - Not changed since it has NULL value in upstream. To remove it we need to investigate if it's safe to do or not.
