Commit adds:
* Implementation of PowerDNS as a provider
* Tests for said implementation
* github.com/ffledgling/pdns-go, which provides go client bindings for
  PowerDNS's HTTP API, as a dependency
* "pdns" as an additional option for the `--provider` flag
* `--pdns-server` and `--pdns-api-key` as additional flags for PowerDNS
  specific configuration

* Add a flag that allows FQDN and Annotations to combine

Old behaviour is kept by default, a new flag is introduced to combine instead of overwrite

Fixes #218

* docs: add fqdn template combine to changelog

* Graceful handling of misconfigure password for dyn

If a bad password is given for provider "dyn" then the next
login attempt is at least 30minutes apart. This prevents an
account from being suspended.

Improve validation of flags for dyn provider. Add test for
ValidateConfig() and Config.String()

Also add --dyn-min-ttl option which sets the lower limit
of a record's TTL. Ignored if 0 (the default).

* docs: add graceful handling of misconfiguration to changelog

* Don't log passwords on start

The two passwords configurable as flags (for infoblox and dyn) are
masked now and not logged.

* docs: add masking sensitive data in logs to changelog

* add "dyn" provider
* add several --dyn-* args to configure Dyn login
* add github.com/nesv/go-dynect/dynect@0.6.0 to Gopkg and vender/ (the client
  of choice by Terraform)
* make externdns.Version public so it can be stored when committing
  zone changes
* add tutorial for Ingress resources and update root README.md file

Dyn REST API is documented here: https://help.dyn.com/dns-api-knowledge-base/

Example usage:

  external-dns \
    --provider=dyn \
    --dyn-customer-name=acme \
    --dyn-username=acme-api \
    --dyn-password=t0pS3cr3t \
    --domain-filter=portal.acme.com \
    --zone-id-filter=acme.com \
    --namespace=my-test-ns \
    --log-level=debug \
    --txt-prefix=_

* Expose inmemory provider to cli

So we can test `--source fake` without needing to touch AWS/Google.

* Add FakeSource

`external-dns --provider inmemory --source fake --dry-run --once`

OR

`external-dns --provider aws --source fake --fqdn-template <hostname suffix> --dry-run --once`

NB: `--fqdn-template` because otherwise we'll default to creating, e.g.,
`abcd.example.com`, which `--provider aws` filters out because you
likely don't have a Zone for `example.com.`  Could also be resolved by
removing the need to use a real provider; the inmemory provider,
perhaps, though it's not entirely hooked up.
