NSX v3 retries conf property used for multiple semantics

[Boden R]

The 'retries' property in the nsx_v3 group of the nsx.ini is currently used in 2 contexts within the nsx v3 plugin:
(a) As the number of times to retry a request IFF the request fails due to StaleRevision exception.
(b) The number of HTTP retries used in the nsx v3 client logic.

We need to not only clarify this usage in the conf, but also introduce a separate conf prop for HTTP retries.

    NSX-v3 HTTP retries conf property

    This patch adds a new conf property to the nsx.ini under the
    nsx_v3 group called http_retries. This value is used for the
    max retries used on HTTP requests. Additionally this patch
    clarifies the use of http_retries vs retries in the conf properties.
    A unit test is also included.
