Ironic needs to know which era of IPA it is talking to. Or conversely, does
ironic want to specify which microversion of IPA it wants to use? (Sorry,
Dmitry, I realize you are cringing.)

With versioning in place we'll have to fix one IPA version in ironic.
Meaning, as soon as we introduce a new feature, we have to explicitly break
compatibility with old ramdisk by requesting a version it does not support.
Even if the feature itself is optional. Or we have to wait some long time
before using new IPA features in ironic. I hate both options.

Well, or we can use some different versioning procedure :)
