add keystone middleware update logic
In order to support changes in the api-paste.ini file for the keystone
middleware of the neutron-api service by subordinates we need a generic
mechanism to pass wsgi middleware data via a relation.
The following approach is used in this change:
- relation data set by subordinates:
{'extra_middleware': [{
'type': 'middleware_type',
'name': 'middleware_name',
'config': {
'setting_1': 'value_1',
'setting_2': 'value_2'}}]}
- there may be many subordinates each with their own set of middleware
all of which should be taken into account
- besides a factory method for middleware other settings can be
specified, therefore, a generic config dictionary is used
- neutron-server has to be restarted as api-paste.ini is read upon
startup of the service
- api-paste.ini rendering code is added along with a template code
containing loops over a list of middleware provided in a context to
construct the following entries:
keystone = [name-1 ... name-m] <default_middleware>
[type-1:name-1]
key-1 = value-1
...
key-n = value-n
...
[type-m:name-m]
key-1 = value-1
...
key-k = value-k
- api-paste.ini defaults are copied from their respective upstream
neutron branches

## HA/Clustering

|

required which provides the corosync back end HA functionality.
|
||||
|
||||
To use virtual IP(s) the clustered nodes must be on the same subnet such that
|
||||
the VIP is a valid IP on the subnet for one of the node's interfaces and each
|

node has an interface in said subnet. The VIP becomes a highly-available API

|

At a minimum, the config option 'vip' must be set in order to use virtual IP

# Additional Middleware Requests by Neutron Plugin Charms
|
||||
|
||||
Some neutron plugins may require additional middleware to be added
|
||||
to api-paste.ini. In order to support that a subordinate may pass
|
||||
extra_middleware via the neutron-plugin-api-subordinate relation.
|
||||
|
||||
Relation data to be set by subordinates:
|
||||
{'extra_middleware': [{
|
||||
'type': 'middleware_type',
|
||||
'name': 'middleware_name',
|
||||
'config': {
|
||||
'setting_1': 'value_1',
|
||||
'setting_2': 'value_2'}}]}
|
||||
|
||||
It would not be correct to do that from your own plugin as this
|
||||
requires the neutron-api service restart which should be handled in
|
||||
this charm.
|
||||
|
||||
The developer guide for Neutron contains a description of the startup
|
||||
process which makes it clear that api-paste.ini is parsed only once
|
||||
in neutron-api's lifetime (see the "WSGI Application" section):
|
||||
|
||||
https://git.openstack.org/cgit/openstack/neutron/tree/doc/source/devref/api_layer.rst#n49
|
||||
|
||||
For the api-paste.ini format in general, please consult PasteDeploy
|
||||
repository docs/index.txt, "Config Format" section:
|
||||
https://bitbucket.org/ianb/pastedeploy
|
||||
|
||||
Classes in loadwsgi.py contain config_prefixes that can be used for
|
||||
middleware types - these are the prefixes the charm code validates
|
||||
passed data against:
