The 'virsh-start' case simply tried to start an already running VM. This
can be easily tested together with the tests for undefining a VM.
For this test the test driver config with multiple VMs comes handy as we
need to test 3 situations when we undefine and stop the VM.

Currently virsh accepts the arguments such as:

<driver name='5' type='6' iothread='7' cache='8' io='9'/>

While making virsh require the flags is technically a breaking change,
there were multiple instances where arguments were added to the argument
list thus changing the order the positional arguments would be
interpreted as. Examples are commits: 7e157858b4, bc5a8090af,

While the virsh option definitions specify (either explicitly after
recent refactors, or implicitly before) whether an argument is
positional or not, the actual parser is way more lax and actually and
allows also arguments which were considered/documented as non-positional
to be filled positionally unless VSH_OFLAG_REQ_OPT is used in the flags.
This creates situations such as 'snapshot-create-as' which has the
following docs:
SYNOPSIS
snapshot-create-as <domain> [--name <string>] [--description <string>]
[--print-xml] [--no-metadata] [--halt] [--disk-only]
[--reuse-external] [--quiesce] [--atomic] [--live] [--validate]
[--memspec <string>] [[--diskspec] <string>]...
Thus showing as if '--name' and '--description' required the option, but
in fact the following happens when only positionals are passed:
$ virsh snapshot-create-as --print-xml 1 2 3 4 5
<domainsnapshot>
<name>2</name>
<description>3</description>
<disks>
<disk name='4'/>
<disk name='5'/>
</disks>
</domainsnapshot>
In the above example e.g. '--memspec' is not populated.
This disconnect makes it impossible to refactor the parser itself and
allows users to write buggy interactions with virsh.
In order to address this we'll be annotating every single of these
unwanted positional options as such so that this doesn't happen in the
future, while still preserving the quirk in the parser.
This patch introduces a tool which outputs list of options which are not
marked as positional but are lacking the VSH_OFLAG_REQ_OPT flag.
This tool will be removed once all the offenders found by it will be
addressed.
