[PATCH 00/22] 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.

Cleber Rosa (22):
  tests/acceptance/boot_linux.py: fix typo on cloudinit error message
  tests/acceptance/boot_linux.py: rename misleading cloudinit method
  Acceptance Tests: remove unnecessary tag from documentation example
  tests/acceptance/virtiofs_submounts.py: use workdir property
  tests/acceptance/virtiofs_submounts.py: do not ask for ssh key
    password
  tests/acceptance/virtiofs_submounts.py: use a virtio-net device
    instead
  tests/acceptance/virtiofs_submounts.py: evaluate string not length
  tests/acceptance/virtiofs_submounts.py: standardize port as integer
  tests/acceptance/virtiofs_submounts.py: required space between IP and
    port
  Python: add utility function for retrieving port redirection
  tests/acceptance/linux_ssh_mips_malta.py: standardize port as integer
  Acceptance tests: clarify ssh connection failure reason
  tests/acceptance/virtiofs_submounts.py: add missing accel tag
  Acceptance Tests: introduce LinuxTest base class
  Acceptance Tests: move useful ssh methods to base class
  Acceptance Tests: introduce method for requiring an accelerator
  Acceptance Tests: fix population of public key in cloudinit image
  Acceptance Tests: set up existing ssh keys by default
  Acceptance Tests: add port redirection for ssh by default
  Acceptance Tests: add basic documentation on LinuxTest base class
  Acceptance Tests: introduce CPU hotplug test
