Can't create namespace using namespace template.

Issue migrated from [https://api.github.com/repos/zero-os/0-templates/issues/165](), opened by @john-kheir

Scenario 1

1- create a zdb service

In [6]: zdb = robot.services.create(
   ...:             template_uid='github.com/zero-os/0-templates/zerodb/0.0.1',
   ...:             service_name='test1',
   ...:             data={'sync': True,
   ...:                   'mode': 'user',
   ...:                   'admin': 'admin',
   ...:                   'path': '/var/cache'})
   ...:                   

In [7]: 

In [7]: zdb.schedule_action('install').wait(die=True, timeout=30)
Out[7]: install

2- Create a namespace service

In [13]: ns2 = robot.services.create(
    ...:            template_uid='github.com/zero-os/0-templates/namespace/0.0.1',
    ...:            service_name='test2',
    ...:            data={'size': 10,
    ...:                  'password': 'password'})
    ...:                  

In [14]: res = ns2.schedule_action('install').wait(die=True, timeout=30)
Traceback (most recent call last):

Notes

@john-kheir can you confirm this is still a valid bug or close it

[BolaNasr]

@zaibon it's look like work good

data = {'sync': True,'mode': 'user','admin': 'admin','path':'/mnt/storagepools/sdd'}

zdb = robot.services.create('github.com/threefoldtech/0-templates/zerodb/0.0.1', 'zerodb1',data=data)
