Add DHIS2 Camel Component.

Target

• I checked that the commit is targeting the correct branch (note that Camel 3 uses camel-3.x, whereas Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I formatted the code using mvn -Pformat,fastinstall install && mvn -Psourcecheck

Thanks for the contribution.

However all the source code must use the ASF license header. So either you need to change this in the PR or we cannot accept the PR to ASF.

Also it would be good to write a bit more in the .doc file what dhis2 is. Just a few lines to explain it to users that do not know.

The code needs to have the ASF License header in all the files.

I removed the javadoc camel-dhis2-api jar, tests were passing. Merged and pushed. Thanks
