Feature external version 'force' option

[frazerh]

Many times it would have been useful to force the update of a document ignoring the version when the version type is external. This is useful when trying to keep the external version in sync with the db optimistic lock version.

Hi Frazerh,

We could build something like this but I want to understand the use case a bit more to make sure we do the proper thing. Currently the external versioning will update a document only if the incoming version is higher than the stored one. I assume that still holds if you use optimistic locking to update your db and ES is updated once the db update succeeds?

Hey @bleskes, yes the above still holds true. On occasion we just need to be able to override this and force and index ignoring the external version.

K. Fair enough. I'll look at the implications of allowing you to force set the version number. Thanks for clarifying.
