Grab Endpoint from PermanentRedirect XML body when this is returned

[marios]

Hi,

please consider this minor edit. The scenario is:

• create a bucket "marios-test-bucket.foo" in ap-north-east-1 and then try to access this from a different server endpoint - such as ap-south-east-1, i.e.:

  client = Aws::S3.new("KEY", "SECRET", {:server=>"s3-ap-southeast-1.amazonaws.com", :connection_mode=>:per_thread})
  bucket = client.bucket("marios-test-bucket.foo")
  bucket.keys

• AWS responds with "301 Moved Permanently":

  >> response
  => #<Net::HTTPMovedPermanently 301 Moved Permanently readbody=true>
  
  >> response.body
  => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n
      <Error>
      <Code>PermanentRedirect</Code>
      <Message>The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.</Message>
      <RequestId>414883F22C6F5799</RequestId>
      <Bucket>marios-test-bucket.foo</Bucket>
      <HostId>CkUSF4xXXgrt8/ggfBrEudibTUn6E0tbPHU72k7FhSeeAeTtTMIiWVywFTGilZja</HostId>
       <Endpoint>marios-test-bucket.foo.s3-ap-northeast-1.amazonaws.com</Endpoint>
       </Error>"

• This minor edit grabs the Endpoint from the response and lets the code retry the connection

I noticed that this code was commented out in the first place (from the parser I mean) and was wondering if there was a reason for that (introduced other problems?),

thanks for your time, marios
