[MSHARED-987] Make use of SISU (#24)

Drop all the reflection hoops and loops, and organize into api-provider layout. Should have NO IMPACT on consumers.

Implement using this SISU based pattern: https://github.com/cstamas/providers In short: SISU loads components lazily, and silently skips component that throws  CNFEx during load. Moreover, Selector "figures our" current environment, more narrowing used delegate.

Changes at high level:
* code reorganization: maven-artifact-transfer-api (new), maven-artifact-transfer-maven-3.0.x (new), maven-artifact-transfer-maven-3.1.x (new) and maven-artifact-transfer (old).
* each module defines it's own (provided) expected environment and cleanly code against it, no reflection, no black magic
* using SISU collection lookup and some minor logic (not yet fully done, works for 3.0/3.1 case but could be improved, 302 repo exception is NOT in yet).
* existing UTs unmodified pass
* existing ITs unmodified pass except for 3.0.5

Benefits:
* each provider module set up it's "own" classpath, no need for reflection and overlapping dependency mess
* dropping a version support is just dropping a module
* adding new version support is just adding a new module
* consumers of m-a-t needs no change
