Modify the Capsule creation opts field.

Modify the Capsule creation opts field from "spec"
to "template". Since now there is already a field
called "spec" in the "spec", which may induce some
misunderstanding for the user.

Also delete capsule_template_version check, since
it is not a useful field.
