This is not used anywhere, and actually cannot be reused anywhere because
of hard-coded document identifiers.
It is too trivial to be worth salvaging, so drop it.

- Text was not converted into HTML.
- HTML was converted into Text before rendering.

- some method names were changed to make them clearer
- new intermediate class 'SlapOSTester'

- method waitInstance moved from runner to communicator
- new simple methods in communicator for request and wait instance
- new methods to modularize runner code
- communicator initialization code moved in runner

Variable name changed from jsonData to json_data.
Old comment deleted.

Some methods in the slapos master communicator no longer exist. The unit test for scalability was updated accordingly.

An update in zope.testbrowser dropped the mechanize dependency used by the browser. Now it uses WebTest instead.

Details of the update: https://pypi.python.org/pypi/zope.testbrowser/5.2.1

- Most of the communication with slapos master is done using the new Slapos Master Communicator instead of Slapos Controller:
  * supply, request, check instance status, check software status.
- Refactor of related methods (waitInstance, isSoftwareReleaseReady, etc.)
- Initialization of communicator: initialize connection to SlapOS usign key and certificate
- General refactor and cleanup: some unnecesary sentences, comments and methods were removed.

- The base of this code comes from some work done by Rafael in here:
    https://lab.nexedi.com/nexedi/slapos.toolbox/blob/master/slapos/agent/tester.py
- Refactor in communication with slap objects for supply and request.
- Added method to check if instance is requested.
- Refactor in log calls.

Each step was still sending emails, not only the controller. This is not
useful.

In the report code, this at_date is used and report generation would
fail if user does not select an `at_date`.

This merge request contains the feature to login in ERP5 with Google Account.

Also, this branch is based on the work done in nexedi/erp5!185

We have a lot of discussion about this changes in nexedi/erp5!179, but with a lot of merge conflicts, a new MR is better to review.

This branch will wake up the discuss of "Moving API Keys from preference to a better place", I can work on it but I am not sure if we have a good design yet.

Any comment is welcome

erp5_trade: Fix Order and Packing List print to use Proxyfields not in Meta forms Hide whitespace change

This prevent to have printout failing when erp5_mrp_item is installed
as it extends Base_viewTradeFieldLibrary but do not contain the fields
for these printouts.

Also, do some trivial cleanup
