#587 pass HTTP headers for WMS,WFS,WMTS,TMS + fix WFS3 test

[justb4]

• WMS was missing HTTP header passing for v 1.1.1.
• added WFS,WMTS,TMS HTTP header passing (was absent)
• WFS3 Test needed small fix because of recent commit for limit param

[cehbrecht]

Fix for issue #587.

[cehbrecht]

@justb4 I'm ok with this PR. Please solve the conflict due to updates.

@tomkralidis Any objections? Can I merge when conflict is solved?

[tomkralidis]

Are we able to update also the CSW and WPS support with this functionality?

[tomkralidis]

Note these fixes are already in master via 9f7bf60

[justb4]

ok, will integrate.

[justb4]

Are we able to update also the CSW and WPS support with this functionality?

Yes, I am aware that these and others also need the same fix:

• CSW: implementation is quite intricate. A central _invoke() though where we should pass headers to openURL() and http_post() (latter needs to merge headers).
• WPS: looks from the code that headers are passed in OK.
• SOS: needs similar fix as WFS
• WCS: needs similar fix as WFS (in 5 WCS-versions!)

IMO 2 options:

1. merge this PR and open new for WPS (if needed), SOS WCS
2. add WPS (if needed), SOS WCS to this PR

I would opt for 1.
NB above checks have failed because of WMTS test.

[justb4]

Above Checks have failed because of a WMTS test failure, could this be lxml related, I use lxml==4.4.1? See below, did not see this error before, did not touch any of the involved code.
@tomkralidis ' commit from yesterday seems unrelated as well, strange. UPDATE: also fails without lxml installed.

@justb4 the latest merge let to a conflict again.

The wps module has already the headers parameter. I'm fine with follow up PRs to add headers to the CSW module etc ...

The current test failures are not related to this PR. Need to treat them separately.

[justb4]

Ok, conflict resolved (was due to my own PR #614, merged). Also added test_tms.py (was missing) with basic tests on URL/main layer from Dutch National SDI, so URL should be stable.
Still failing tests but test_tms.py should be ok.

[cehbrecht]

@justb4 merged :)
