Support HTTPS for proxy ows (wps) services

[cehbrecht]

The current twitcher implementation fails for https services with self-signed certificates.

There is already a patch available which needs to be integrated:
Ouranosinc@b42e052

See also issue #46.

[cehbrecht]

@tlvu @huard I try to integrate the patch from ouranos.

[tlvu]

@cehbrecht FYI, I tried the patch from Francis in a full PAVICS deployment and it works.

[cehbrecht]

@tlvu @huard what do you think about PR #55?

[huard]

I'm out of my depth, but looks good.

[cehbrecht]

Well, I merge ... we can figure out later.

[cehbrecht]

fixed by PR #55.

[tlvu]

@cehbrecht oops sorry, I didn't realized you wanted a PR review since I was not in the reviewer list. At my previous workplace, we were explicit in requesting review by adding the intended person(s) to the reviewers list.

[tlvu]

@cehbrecht wow patch is so different than the original patch ! Don't think I would be able to review either. Fun time ahead for merging the difference between this version of twitcher and the version in ouranosinc :(

[cehbrecht]

@tlvu in the birdhouse patch the ssl_verify is a parameter in the service registry, so you can decide for each WPS service.

[tlvu]

@cehbrecht ah nice! Disabling SSL certificate verification only for those WPS services that are behind self-signed.
