Dump: Add token to host dump entries

This commit introduces a token field to the
xyz.openbmc_project.Dump.Entry.System and
com.ibm.Dump.Entry.Resource interfaces. This token is
exchanged from the host when a request to create a dump
is made. The token can be used to identify the dump
entry once the collection is completed. This addition
enhances the tracking of dump entries for the dumps
collected in the host.
