Disable jersey2 jsonp/moxy auto discovery

[mattnelson]

Disable moxy/jsonp autodiscovery as the eureka client usage leverages an explicitly registered message body reader/writer.

When moxy or another json processor(jsonp) are on the classpath, they will be autodiscovered and registered into the transport/application clients which causes errors as those other providers take precedence over the DiscoveryJerseyProvider.

@troshko111 Could I get review on this?

[troshko111]

Thanks @mattnelson!

[mattnelson]

@troshko111 Do know when this will be released?

[troshko111]

I have no problem releasing right now, it seems pretty safe to me. In general, feel free to mention if it's important to release close to the PR merge, more than happy to accomodate.

EDIT 1: kicked off one.
EDIT 2: released.
