David Pilato 9b247f9828 Fix remove of azure files
Probably when we updated Azure SDK, we introduced a regression.
Actually, we are not able to remove files anymore.

For example, if you register a new azure repository, the snapshot service tries to create a temp file and then remove it.
Removing does not work and you can see in logs:

```
[2016-05-18 11:03:24,914][WARN ][org.elasticsearch.cloud.azure.blobstore] [azure] can not remove [tests-ilmRPJ8URU-sh18yj38O6g/] in container {elasticsearch-snapshots}: The specified blob does not exist.
```

This fix deals with that. It now list all the files in a flatten mode, remove in the full URL the server and the container name.

As an example, when you are removing a blob which full name is `https://dpi24329.blob.core.windows.net/elasticsearch-snapshots/bar/test` you need to actually call Azure SDK with `bar/test` as the path, `elasticsearch-snapshots` is the container.

To run the test, you need to pass some parameters: `-Dtests.thirdparty=true -Dtests.config=/path/to/elasticsearch.yml`

Where `elasticsearch.yml` contains something like:

```
cloud.azure.storage.default.account: account
cloud.azure.storage.default.key: key
```
