post-install of snap toolbox

[nilshempelmann]

the kingfisher/requirements/snap_install.sh still contains hard coded pathes. ( related to #6 )

python can not be configured in the right way (may be not compatible with python3.6??)

Python configuration error: Python configuration failed.

SNAP is suppored only with python 2.7 3.3 or 3.4 !
Needs to be pinned in the environment.yml

welcome back to the hell of dependencies:

UnsatisfiableError: The following specifications were found to be in conflict:

• python=3.4
• pywps=4.1 -> python[version='>=3.6,<3.7.0a0'] -> openssl[version='>=1.1.1a,<1.1.2a']
• pywps=4.1 -> python[version='>=3.6,<3.7.0a0'] -> tk[version='>=8.6.8,<8.7.0a0']
  Use "conda info " to see the dependencies for each package.

this is not a problem of pywps. You can add the constrain python<=3.4 to the conda environment.yml. You should also update the Python versions tested on travis: 2.7, 3.4.

But hopefully snap is going to support a recent python 3.x version.

we are running snappy with the current last release: The current version is 6.0.0 (15.01.2018 15:25 UTC).

Well, for some reason pywps is build for a specific python version. Not sure if I can change this. Python 3.4 is also quite old and I don't know if I can manage to build pywps against it (due to dependencies). So, we need to stick with python 2.7 for now ... but better prepare code for 3.x (use six).

That reminds me to enable 3.6 check on travis ... this should work as long snappy is not called.

priority to focus on sentinelhub-py
