Add NotAllowed error to dump create and initiateOffload.

Certain dump creation may not be allowed during all the time
so adding a new error
"xyz.openbmc_project.Common.Error.NotAllowed" to the list of
errors, similarly dump offload also cannot be done always so
adding that error to initiateOffload too.
