Merge remote-tracking branch 'remotes/dgilbert/tags/pull-migration-20200325b' into staging
Combo Migration/HMP/virtiofs pull
Small fixes all around.
Ones that are noticeable:
a) Igor's migration compatibility fix affecting older machine types
has been seen in the wild
b) Philippe's autconverge fix should fix an intermittently
failing migration test.
c) Mao's makes a small change to the output of 'info
migrate_parameters' for tls-authz.
