Missed variable in delete function in REST API calles

[omarbenazza]

Hello,

This is my first issue report in github, please consider my humble report,
In sdk\app_template_csclient\csclient script code, delete function needs a variable called value in parameters:

                                           def delete(self, base, query=''):

It should be like:

                                   def delete(self, base, value='', query=''):

I think this issue can be found in other csclient files in other directories.

Regards,

Omar
