Add datasource type "hosts" for api/nutanix/v3/hosts endpoint

Is your feature request related to a problem? Please describe.
api/nutanix/v3/hosts endpoint provides a lot of information about the host. For example if you have a cluster that has GPUs installed, v3/hosts will provide information about the device id, mode of operation of the GPU etc.., this information is needed if we want to create a virtual machine with gpu attached.

Hello @chandru-tkc I added the data sources to retrieve the host data, you can check it out on the PR #116.
