Outdated doc for Kilo about configuring powerdns backend

[Anton Galitsyn]

Hi!

Page doc/source/backends/powerdns.rst seems to be outdated for Kilo release, because commands llike designate-manage powerdns sync is not working anymore. It should be designate-manage powerdns sync {{ pool_target_id }}.

Also information about real config settings for powerdns are missing. Here is example config which works:

[service:central]
max_domain_name_len = 255
max_recordset_name_len = 255
default_pool_id = '{{ designate_default_pool_id }}'

[service:pool_manager]
pool_id = {{ designate_default_pool_id }}

[pool:{{ designate_default_pool_id }}]
targets = {{ designate_default_pool_target_id }}

[pool_target:{{ designate_default_pool_target_id }}]
type = powerdns
options = connection: mysql://pdns:{{ powerdns_mysql_password }}@{{ galera_address }}/pdns?charset=utf8, idle_timeout: 3600, max_retries: 10, retry_interval: 10

Kilo is reaching eol - and there has been some docs updates recently that should cover this.
