GSLB "get_all_gslb" just repeats parent zone name

[brentrjones]

When trying to list all GSLBs in a zone, the 'get_all_gslb' function just repeats the parent zone name for N instances of GSLB under the zone.

To reproduce:
my_zone = Zone('mydomain.com') all_gslb = my_zone.get_all_gslb() print(all_gslb)

Will just print
[<GSLB>: mydomain.com., <GSLB>: mydomain.com., <GSLB>: mydomain.com., <GSLB>: mydomain.com., <GSLB>: mydomain.com., <GSLB>: mydomain.com., <GSLB>: mydomain.com., <GSLB>: mydomain.com.]

In dyn/zones.py, offending section removes the returned zone and fqdn:

def get_all_gslb(self): """Retrieve a list of all :class:GSLB services associated with this :class:Zone`

    :return: A :class:`List` of :class:`GSLB` Services
    """
    uri = '/GSLB/{}/'.format(self._name)
    api_args = {'detail': 'Y'}
    response = DynectSession.get_session().execute(uri, 'GET', api_args)
    gslbs = []
    for gslb_svc in response['data']:
        del gslb_svc['zone']
        del gslb_svc['fqdn']
        gslbs.append(GSLB(self._name, self._fqdn, api=False, **gslb_svc))
    return gslbs`

I'll see if I can restructure that to return intended results, but a lot of the functions seem to be copy-pastad and I'd like to fix all of them, too
