Support parameters along with proxy_pass now w/ tests

[tfhartmann]

Added tests to @mark0n PR for #764

@mhaskel I think this is what you were looking for 😄

[mark0n]

Unfortunately I didn't find time to implement the tests myself. Thanks @tfhartmann! I really appreciate that you are pushing this forward :-)

[igalic]

this will need a rebase now…

[igalic]

now that i've merged a different params patch _
#910

[tfhartmann]

no worries, I'll give it a rebase :)

[igalic]

\o/ thank you and i'm sorry /o\

[tfhartmann]

@igalic @hunner @mhaskel Is there a preferred method to pass these parameters? When I rebase, should I keep the subhash/array method that @mark0n used it #764 or the string method that @mkobel used in #910 ?

[mark0n]

I also implemented a simple string method first but after a request by @apenney #764 (comment) I moved to the subhash/array method. This reflects the structure of the data better and thus seems cleaner to me.

[mkobel]

@tfhartmann @igalic @mhaskel @mark0n The subhash/array method is IMHO cleaner. But this way you cannot add these parameters: nocanon interpolate noquery (http://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypass)

[mark0n]

@mkobel that's correct you cannot add them as parameters because they aren't parameters but keywords (using the language of the Apache documentation). Note that this PR supports both.

[mkobel]

@mark0n Thank you for your clarification!

[tfhartmann]

Thanks guys! I rebased and pushed to my branch :)
