when try keystone_client.tenants.get
got error,
isn't this method for all kinds of function?
>>> m = "4c9a0da00b904422a23341e35be7f8d7"
>>> ten = checkexception(keystone_client.tenants.get,
>>> tenant_id=checkexception(m.encode,encoding='ascii',errors='ignore'))
Unexpected error: <class 'keystoneclient.apiclient.exceptions.NotFound'>
None
