[PATCH v3 0/9] tests: introduce testing coverage for TLS with migration

["Daniel P. Berrangé" <berrange@redhat.com>]

This significantly expands the migration test suite to cover testing
with TLS over TCP and UNIX sockets, with both PSK (pre shared keys)
and x509 credentials, and for both single and multifd scenarios.

It identified one bug in handling PSK credentials with UNIX sockets,
but other than that everything was operating as expected.

To minimize the impact on code duplication alopt of refactoring is
done of the migration tests to introduce a common helper for running
the migration process. The various tests mostly just have to provide
a callback to set a few parameters/capabilities before migration
starts, and sometimes a callback to cleanup or validate after
completion/failure.

Changed in v3:

  - Trivial rebase dropping already merged patches

Changed in v2:

  - Use structs to pass around most parameters
  - Hide expected errors from stderr
