Nsxramlclient

This version of nsxramlclient added support for repeating keys in the XML body without nested structure bellow. Before v2.0.1 nsxramlclient only supports repeating keys in the XML body if these repeating key themself hold multiple keys bellow them (nesting). This patch adds the support for repeating keys that only hold a values bellow them and no nested structure. This was needed to support the API call to create secondary IP Addresses on ESG router interfaces

This version of nsxramlclient is needed to support the new format of the nsxraml spec on http://github.com/vmware/nsxraml that introduced a breaking change in the way schemas are handled. In the new NSX-v RAML spec schemas are now real schemas that can be used to check the correctness of your XML document. In the earlier versions the schema was used to return an XML example as a python Dict. The new way of retrieving the XML example dict is by using the new method introduced in the 2.0 version named extract_resource_body_example

This release introduces new helper methods:
- read_all_pages:
This Method reads all pages from the API Get for the ['virtualWires', 'pagedEdgeList'] displayNames. This e.g. helps to collect all logical switches present in the system without having to know the needed page file size
- normalize_list_return:
There are API calls in NSX-v were you are getting a None object if no Object is present, a Dict type when only one Object is present, and a List of Dicts when more than one Object is present. E.g. for the retrieval of logical switches. When passing the API return to this function it will normalize the return to be a list. If the input is a None Object (no Object exists in NSX-v) an empty list is return. When one Object is found, a List with the one Dict is returned, when the input is a list, it is returned back unmodified
