[PATCH] KVM test: Pass the test parameters through the command line

From: Jason Wang <jasowang@redhat.com>

The patch tries to make using kvm-autotest much more easier by
enabling the ability of passing the test parameters from command line
directly through --args="key1=value1 key2=value2 ... keyN=valueN".

The idea is simple, autotest test pass the additional parameters
through args, and the control file analyzes them and generate the
configuration string for kvm_config.

The keywords "only" and "no" were introduced to limit the variants,
for each "only=variant1" the control file would generate a line
"only variant1", same for "no". For others, "key = value" is
generated.

User still need to be familiar with the test parameters in order to
get the intended test matrix.

Change from V3:
Use a slightly bigger subset of the config file language
by allowing "no" to limit the amount of variants.

Change from V2:
Use the args exported by autotest.
Analyze the cmd parameters in control and drop control.cli.
Drop test_cli.cfg.sample so there's no default variants.
Add "only" which is used to limit the varaints.

Change from V1:
Drop the wrapper method and use the control file directly.
