pdns example pools.yaml snippet does not explain the connection string

[Graham Hayes]

targets:
    - type: powerdns
      description: PowerDNS Database Cluster

      # List out the designate-mdns servers from which PowerDNS servers should
      # request zone transfers (AXFRs) from.
      masters:
        - host: 192.0.2.1
          port: 5354

      # PowerDNS Configuration options
      options:
        host: 192.0.2.1
        port: 53
        connection: 'mysql+pymysql://designate:password@127.0.0.1/designate_pdns?charset=utf8'

this should have a comment above the connection snippet to explain that this is for the pdns database, not the designate database.
