Improve the ec2_snapshot argument spec and docs

ec2_snapshot got missed when moving to a common argument spec.

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.
