Adding the args parameter to BaseVM's __init__.
We will shortly need to pass more parameters to the class
so let's just pass args rather than growing the parameter list.

Added use of a configuration to tests/vm/basevm.py.
The configuration provides parameters used to configure a VM.
This allows for providing alternate configurations to the VM being
created/launched. cpu, machine, memory, and NUMA configuration are all
examples of configuration which we might want to vary on the VM being created
or launched.
This will for example allow for creating an aarch64 vm.

Changes to tests/vm/basevm.py to allow accepting a configuration file
as a parameter. Allows for specifying VM options such as
cpu, machine, memory, and arbitrary qemu arguments for specifying options
such as NUMA configuration.
Also added an example conf_example_aarch64.yml and conf_example_x86.yml.

Add a common Ubuntu python module and make use of
it with the ubuntu.i386 script.
This is preparation for adding an Ubuntu script
ubuntu.aarch64. Splitting out the common
logic such as build_image() will reduce duplication.

ubuntu.aarch64 provides a script to create an Ubuntu 18.04 VM.
Another new file is also added aarch64vm.py, which is a module with
common methods used by aarch64 VMs, such as how to create the
flash images.

This change converts existing scripts to using for example self.ROOT_PASS,
to self._config['root_pass'].
We made similar changes for GUEST_USER, and GUEST_PASS.
This allows us also to remove the change in basevm.py,
which adds __getattr__ for backwards compatibility.

We add the ConsoleSocket object, which has a socket interface
and which will consume all arriving characters on the
socket, placing them into an in memory buffer.
This will also provide those chars via recv() as
would a regular socket.
ConsoleSocket also has the option of dumping
the console bytes to a log file.
We also give QEMUMachine the option of using ConsoleSocket
to drain and to use for logging console to a file.
By default QEMUMachine does not use ConsoleSocket.
This is added in preparation for use by basevm.py in a later commit.
This is a workaround we found was needed for basevm.py since
there is a known issue where QEMU will hang waiting
for console characters to be consumed.

This adds support to basevm.py so that we always
drain the console chars. This makes use of
support added in an earlier commit that allows
QEMUMachine to use the ConsoleSocket.
This is a workaround we found was needed since
there is a known issue where QEMU will hang waiting
for console characters to be consumed.
We also added the option of logging the console to a file.
LOG_CONSOLE=1 will now log the output to a file.
