feat: Add ability to import user password credentials

[samcgardner]

This change implements a very simple way of adding a user to Kratos with a known password, either in clear text or in one of the supported hashes. The user can also be added in a Verified status. This is intended to support a simple way of importing an existing user database.

I am submitting on behalf of a colleague due to previously discussed issues with internal approval.

Any update on this? We really need this feature. Also, some support for extending hasher implementations would be great (perhaps in form of an external API call), but this is great for now.

Hey Alan,

That being said this is an important feature that will soon land, please be patient 🙏
We are also always open to contributions 👍

Hey ORY team, I just want to check you don't need any further input from me to drive this forward

Hey, I was looking into this issue today. It is a great starting point but there is still lots of work to be done. Besides tests, I think that the API format needs improvement to be more compatible with the default schema. It would also be good to be able to import some other credentials than the password. I saw that there are some changes to the packages that we can probably avoid (I suppose those were added due to some circular dependencies). I'm basing a new PR off of this one and see how far we get and tag you as a reviewer @samcgardner ? :)
