Description

It's standard procedure to accept the big contribution with iCLA granted in ASF.
We should list this information when the contributor send the PR by specifying a PR template for github. It could be annoying for the experienced contributors, but it could save us some time for the new contributors.
Here is a draft I have, please add comment for it.

 - [ ] Make sure there is a [JIRA issue](https://issues.apache.org/jira/browse/CAMEL) filed for the change (usually before you start working on it).  Trivial changes like typos do not require a JIRA issue.  Your pull request should address just this issue, without pulling in other changes.
 - [ ] Each commit in the pull request should have a meaningful subject line and body.
 - [ ] Format the pull request title like `[CAMEL-XXX] Fixes bug in camel-file component`, where you replace `CAMEL-XXX` with the appropriate JIRA issue.
 - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
 - [ ] Run `mvn clean install` in your module to make sure basic checks pass. A more thorough check will be performed on your pull request automatically.
 - [ ] If this contribution is large, please file an Apache [Individual Contributor License Agreement](https://www.apache.org/licenses/icla.pdf).
