 Title: #5312: Move where the restore state is marked during IPA server upgrade
Action: opened

PR body:
"""
There is still some exposure to killing in a bad place. This was
reproduced by killing the process in the parser.parse() call within
__restore_config (line 230) so the values were restored from the
backup but the new dse.ldif never written or copied. But the values
had already been restored from the state file.

I'm not sure this can ever be 100% bullet-proof since it can be
externally killed but if rather than calling restore_state() on the
values in __restore_config we use get_state() which will peek at the
values in the state file without removing them. Then the last step
is to pop upgrade-in-progress and then the rest.

If the values have been restored and the new ldif written and copied
then it's only upgrade-in-progress that really matters. The rest will
be overwritten.
