[midPoint] Scripted REST Connector

[Arda Nural]

Thank you for the wiki page and modified connector. Before seeing your
reply, I added the http-builder dependency again, excluding the conflicting
dependencies. Now I returned back and using the new connector jar you
provided. This will help us for the short term.  Soon, we should start
migrating to polygon based REST connectors.

Hi,

This is a nasty issue. The http-builder package caused a lot of trouble.
This package was part of midPoint until approx 3.3. But in 3.4 or 3.4.1 I
had to remove it. It is not used anywhere in midPoint. And the http-builder
package seem to be unmaintained. That may be the reason that it causes
problems with dependency convergence. I couldn't find any better way than to
remove it from midPoint. At that time I though that removing it is
harmless - as it was not used anywhere ...

Only (much) later I have learned that it is needed by scripted REST
connector ...

We were exploring the situation few weeks ago. And there are actually two
results:

1. Scripted REST connector is a bad idea. Yes, it is good for prototyping.
But it is a maintenance nightmare. It is difficult to organize the scripts,
it is almost impossible to do proper connector versioning and so on. So our
decision was to abandon the scripted REST - at least for the connectors that
we will be creating. Instead of that we have created a superclass for a
REST-based connector
(https://github.com/Evolveum/polygon/tree/master/connector-rest). So now we
can easily create maintainable Java REST connectors.

2. The http-builder dependency should be a dependency of the scripted REST
connector and not a dependency of midPoint. Although we now officially frown
upon the Scripted REST approach, we still have some legacy set of connectors
that need to work (until we migrate them).
Therefore I have created a new version of the Scripted REST connector that
has the dependency fixed:

http://nexus.evolveum.com/nexus/content/groups/connectors/org/forgerock/openicf/connectors/scriptedrest-connector/1.1.1.e2/scriptedrest-connector-1.1.1.e2.jar

If you switch to this version then everything should work for you. But most
likely this is the last version of scrited REST connector that there ever
will be (at least from our side).

(I'm going to put that explanantion also in wiki. I have realized it is not
there)
