share protocols can not be disabled

[Valeriy Ponomaryov]

We may want to disable some share protocols with our custom Manila installation when we have enabled share drivers that support only some specific protocols and not all of them.

So, we should be able to disable any protocol.

    Add possibility to enable/disable some share protocols

    It is useful in case we use share backends that do not implement some share
    protocol or want to disable something for some other reason. For the moment,
    there is no share driver that supports all share protocols in Manila.
