Blob breakLease proxy API signature incorrect

[jcookems]

Dev Estimate: 1
Test Estimate: 1

The current breakLease API is this:

public void breakLease(String container, String blob, String leaseId)

However, according to http://msdn.microsoft.com/en-us/library/windowsazure/ee691972,

x-ms-lease-action: <acquire | renew | release | break>
...
Break:
... the request is not required to specify a matching lease ID.
... the response indicates the interval in seconds until a new lease may be acquired.

This means that

1. The leaseId parameter should be removed
2. The function should return an object that includes a LeaseTime property.

We need to fix this for PHP as well!

Begun implementation. Parameter has been removed, need to add return value next.

Added return value, waiting on code review.
