Implemented dynamic selection of NoContentException provider to back support of JaxRS 1.x

[Spikhalskiy]

As discussed here #90

Implemented approach with a dynamic selection of NoContentException creation strategy.
I did it in a bit another fashion than it was implemented previously to use reflection only once for a strategy selection, not for a creation of each instance.

Result:

CONFIG:     Provider found: class com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider

During a container start.

Also, here https://github.com/Spikhalskiy/jackson-jaxrs-providers-compat-tests
is a separate module that depends on the old JaxRs and Jersey dependencies version. Test there fails on current master and works fine with this PR merged. Feel free to just pick it up as one more github.com/Jackson module.

Looks good. I wonder what'd be the easiest way to merge this into 2.8 branch?

[Spikhalskiy]

@cowtowncoder I'm not sure what do you mean, just cherry-pick is fine: #92 If you want to have an ability to merge 2.8 to master - just merge this second PR maybe and merge 2.8 -> master?

[cowtowncoder]

@Spikhalskiy yea, need to learn how to cherry pick from PR (of different repo) to non-master branch. Have had bit of trouble history trying to use git for non-trivial things.

[cowtowncoder]

... and cherry-pick attempt fails by claiming "merge" is needed. Sigh.

[Spikhalskiy]

What do you do? I checked out new master, switched to 2.8, did git cherry-pick ae9914dcac7831510b1a3f4ef6a3bcd6b581b0e9 and it works. 2.8 has this commit after this command too.

@Spikhalskiy maybe I chose wrong hash... I'll try again.

@Spikhalskiy thanks, that was it! Will be in 2.8.5 now.
