Merge lp:~jtv/maas/1.5-bug-1302772 into lp:maas/1.5

[Jeroen T. Vermeulen]

Backport trunk r2235: Continue to accept (but do not use) the old “boot” section in pserv.yaml. Otherwise, upgrade breaks while parsing this file.

[Andres Rodriguez (andreserl)]

There are conflicts in the branch

review: Needs Fixing

[Jeroen T. Vermeulen (jtv)]

Self-approving straight backport. The conflicts earlier happened because somehow the MP was targeted at trunk instead of 1.5. I have no idea why — I definitely went through the motions to select 1.5, finding it with a search and then selecting it.
