Code Issues Proposed changes

Use juju secrets for admin/service passwords

Browse Source 
Currently the admin and service passwords are saved
in plain text in the relation data. Use juju secrets
and save the secret id in the relation data.

Make zaza-smoke-tests job optional as this patch is
not compatible with glance-k8s on channel edge.

"""IdentityServiceProvides and Requires module.
This library contains the Requires and Provides classes for handling
the identity_service interface.
Import `IdentityServiceRequires` in your charm, with the charm object and the
relation name:
- self
- "identity_service"
Also provide additional parameters to the charm object:
- service
- internal_url
- public_url
- admin_url
- region
- username
- vhost
Two events are also available to respond to:
- connected
- ready
- goneaway
A basic example showing the usage of this relation follows:
```
from charms.keystone_k8s.v1.identity_service import IdentityServiceRequires
class IdentityServiceClientCharm(CharmBase):
def __init__(self, *args):
super().__init__(*args)
# IdentityService Requires
self.identity_service = IdentityServiceRequires(
self, "identity_service",
service = "my-service"
internal_url = "http://internal-url"
public_url = "http://public-url"
admin_url = "http://admin-url"
region = "region"
)
self.framework.observe(
self.identity_service.on.connected, self._on_identity_service_connected)
self.framework.observe(
self.identity_service.on.ready, self._on_identity_service_ready)
self.framework.observe(
self.identity_service.on.goneaway, self._on_identity_service_goneaway)
def _on_identity_service_connected(self, event):
'''React to the IdentityService connected event.
This event happens when n IdentityService relation is added to the
model before credentials etc have been provided.
'''
# Do something before the relation is complete
pass
def _on_identity_service_ready(self, event):
'''React to the IdentityService ready event.
The IdentityService interface will use the provided config for the
request to the identity server.
'''
# IdentityService Relation is ready. Do something with the completed relation.
pass
def _on_identity_service_goneaway(self, event):
'''React to the IdentityService goneaway event.
This event happens when an IdentityService relation is removed.
'''
# IdentityService Relation has goneaway. shutdown services or suchlike
pass
```
