OGC service params should be case insensitive

[nickdos]

Currently some OGC services (e.g. WMS tiles) require the OGC params to be provided in upper case. The problem is that recent versions of Leaflet send the various dynamic params in lower case by default and the tiles fail to load. There is an option in Leaflet to send params in upper case (uppercase: true) but this sends all params in upper case and then the ALA-defined params are ignored. E.g. LAT and LON are ignored, as they are required to sent in lowercase!

The OGC spec says params should not be case sensitive:

@ansell suggested:

This option using a Filter looks like it could possibly be supportable by biocache-service without changing the way RequestParam works https://stackoverflow.com/questions/29531786/making-a-request-parameter-binding-case-insensitive/29533456

Fix for this is on docvalues branch.

@adam-collins ive reverted the commits for case-insensitivity as they broke WMS

@adam-collins @djtfmartin this issue is affecting us (see here), and I'd like to take a crack at fixing it. If I put together a PR, would it be possible for you to review, (and if you're happy with it) merge and release?

[djtfmartin]

Thanks @KeyboardSounds ! Yes that would be great.
