Issue:
Broken backwards compatibility for account usage and limits
Motivation
----------
Due to the change from simple limits/usage to local/global usage and limits, the backwards compatibility for old clients is currently broken. This is due to the fact that the REST endpoints where changed from
```
    '/(.+)/limits', 'AccountLimits',
    '/(.+)/limits/(.+)', 'AccountLimits',
    '/(.+)/usage/', 'Usage1',
    '/(.+)/usage/(.+)', 'Usage2',
```
to
```
    '/(.+)/limits/local', 'LocalAccountLimits',
    '/(.+)/limits/local/(.+)', 'LocalAccountLimits',
    '/(.+)/limits/global', 'GlobalAccountLimits',
    '/(.+)/limits/global/(.+)', 'GlobalAccountLimits',
```
thus the required endpoints are missing for old clients. 

Modification
------------
The endpoints need to be re-added and pointing to the local version of the usage/limit.

Lifetime Model: Limit the duration of the extension to one year in the UI
Motivation
----------
Lifetime Model : Limit the duration of the extension to one year in the UI
