Keystone V3 Support

[Gareth Woolridge]

In starting to look at redeploying error-tracker to PS5 it was discovered that the charms and services do not support Keystone v3 which is a hard requirement for deployment on a modern OpenStack.

At a minimum the charms for fetching code from Swift, and the apps pushing/fetching cores from Swift/RadosGW are missing:

OS_PROJECT_NAME
OS_IDENTITY_API_VERSION

A novarc for such a cloud would likely set these:

OS_PROJECT_NAME=${OS_TENANT_NAME}
OS_IDENTITY_API_VERSION=3

I'm not terribly familiar with swift but given that --os-identity-api-version "defaults to env[ST_AUTH_VERSION], env[OS_AUTH_VERSION], env[OS_IDENTITY_API_VERSION] or 1.0". Are any changes actually necessary when calling /usr/bin/swift?

[Brian Murray (brian-murray)]

daisy/submit_core.py and daisy/retracer.py both set auth_version to 2.0 so that'll need changing.

The switch to keystone v3 has been deployed.
