Add method to bulk delete keypairs

[James E. Blair]

A user should be able to delete keypairs in bulk. I'm currently deleting about 100,000 of them and expect it to take about 13 hours.

[Joe Gordon (jogo)]

there are two ways to handle this, and I think we should do both:

* support deleting multiple keypairs in a single request (help get around rate limiting)
* add option to delete all keypairs

[Sahid Orentino (sahid-ferdjaoui)]

I have confirmed it and added it in wishlist because: currently the API does not handle delete by passing multiple keys in a single request and does not have an api to remove all keys. (in relation with the comment of Joe)

[Sahid Orentino (sahid-ferdjaoui)]

Joe, does this feature has to be in a bp or can we work on it by referencing this bug?

[Sahid Orentino (sahid-ferdjaoui)]

Because we have to update the API, the client needs as well to be updated so I have confirmed, and add the bug in wishlist.

[Markus Zoeller (markus_z) (mzoeller)]

This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.

In case you want to work on that, consider writing a blueprints [1] and spec [2]. I'll recommend to read [3] if not yet done. The effort to implement the requested feature is then driven only by the blueprint (and spec).
