lvg module bugfix on vg_options patch

When no vg_options are passed to the module, 'vg_options' still exists

Improve the ec2_snapshot argument spec and docs

ec2_snapshot got missed when moving to a common argument spec.
It could already make use of the capabilities (as it uses
ec2_connect) and the documentation suggested it supported the
common argument spec (thanks to the documentation fragment work)
so it was just a matter of fixing the argument spec.

Removed unnecessary documentation for profile and security_token
that is covered by documentation fragment

Also removed spurious documentation flags (default: null, aliases: [])
which aren't needed.
