[PATCH for 7.1 v1 0/6] testing fixes and doc tweak pre-PR

[Alex Bennée]

Hi,

This is a small subset of testing fixes to improve the stability of
the CI. The first ensure all jobs have a timeout (default 120s) and
then we have Thomas'  excellent work to speed up the migration test
which was the source of a number of gitlab timeouts. Finally a little
bit of extra manual text to point users in the right direction when
defining block devices.

Only one patch needs review before the PR:

 - tests/avocado: push default timeout to QemuBaseTest
