[PATCH v2 00/10] Acceptance Test: introduce base class for Linux based tests

[Cleber Rosa]

This introduces a base class for tests that need to interact with a
Linux guest.  It generalizes the "boot_linux.py" code, already been
used by the "virtiofs_submounts.py" and also SSH related code being
used by that and "linux_ssh_mips_malta.py".

While at it, a number of fixes on hopeful improvements to those tests
were added.

Changes from v1:

* Majority of v1 patches have been merged.

* New patches:
  - Acceptance Tests: make username/password configurable
  - Acceptance Tests: set up SSH connection by default after boot for LinuxTest
  - tests/acceptance/virtiofs_submounts.py: remove launch_vm()

* Allowed for the configuration of the network device type (defaulting
  to virtio-net) [Phil]

* Fix module name typo (s/qemu.util/qemu.utils/) in the commit message
  [John]

* Tests based on LinuxTest will have the SSH connection already prepared
