ServiceMix should not use non-free json.org

The json.org version of the BSD license is problematic because it imposes constraints on the downstream consumer by including a constraint on field of endeavor that the software "not be used for evil". Debian and Google, for instance, won't consume anything with this license:

• https://wiki.debian.org/qa.debian.org/jsonevil
• https://www.cnet.com/news/dont-be-evil-google-spurns-no-evil-software/

The json license has been moved to category X. We should replace the usage of this library by other implementation which is compliant with Apache license (https://wiki.debian.org/qa.debian.org/jsonevil)
