software/slapos-sr-testing: generate an environment script

Using an script to set the environment is easier to use, but the main
reason is that if we want to be able to use shared part from outer
slapos (like when using in theia or slaprunner), the working directory
for test must be contained in the instance directory of the outer
slapos, so that when we run slapos node prune in the outer slapos this
command can see that shared parts are used.

## Environment variables
The `environment-script` set all variabels except `SLAPOS_TEST_DEBUG` and `SLAPOS_TEST_VERBOSE` for you, but for reference, here is the list of variables which control the test runner:
| Variable | Description |
| --- | --- |
| `SLAPOS_TEST_IPV6` | ipv6 used by this instance. Usually you want to use a global address here to be able to connect to this instance. |

### Test pass locally but fail on test nodes, what can I do ?

At the end of the test, a snapshot of the slapos instances is created. Sometimes examining the log files can help understanding what went wrong.
Most of the time, problems are because on test nodes paths are very long. One advanced technique to reproduce the problem in your development environment is to set `SLAPOS_TEST_WORKING_DIR` environment variable to a path with the same length as the ones on test nodes.
One way to make instances uses a slightly shorter path is to define `__partition_reference__` class attribute, so that the instances uses this as prefix instead of the class name.
