   Issue: https://github.com/apache/camel-quarkus/issues/3579
   
   Requires https://issues.apache.org/jira/browse/CAMEL-17764 (already fixed) 
for proper native clustered test, hence `camel-main` branch is sed as the base.
   
   I faced several problems, which may not be resolved in this PR completely:
   
   1. Clustering. Quarkus in their extension forces users to use quarkus's 
`application.properties` to define clustering. (see 
https://quarkus.io/guides/quartz) This approach allows to define and configure 
quartz scheduler and avoid use of `c3p0` library (which is used by quartz 
clustering capability). To keep an option to define clustering in the quartz 
itself (using `quartz.properties`)  I  had to add `c3p0` and improve extension 
to allow native run with this library.
   
   Currently there are a few limitations. 
   - Oracle db type won't work in native, because it requires registration for 
reflection (possible) which references `oracle.sql.BLOB` which I'm not sure how 
to correctly handle (there is a **todo** in `QuartzProcessor`)
   - Quarkus sets property `org.quartz.jobStore.useProperties` to `true` by 
substitution, so it can not be changed. Which is the reason why this issue has 
to be fixed in the camel codebase - 
https://issues.apache.org/jira/browse/CAMEL-17764 (already fixed)
   
   2. I used a fixed port for postgrresql db, because there is no obvious way, 
how to use variable in `quartz.properties` (where port has to be passed for db 
configuration, Unfortunately agroal DS can not be used, because the only way 
how to pass DS int oquartz is by JNDI - quarkus supports only CDI)
   
   3. With this PR users can use quarkus's clustering (tested by quarkus) or 
Quartz's clustering (tested by this PR).
   
   To summarize:
   
   - c3p0 dependency was added
   - clustering by `quartz.properties` is tested
   - so far oracle won't work in native
   - fixed port is used for postgresql db in the test (I used postresql db, 
because quarkus is using h2 for testing -> which brings more coverage)
   
   <!-- Uncomment and fill this section if your PR is not trivial
   [ ] An issue should be filed for the change unless this is a trivial change 
(fixing a typo or similar). One issue should ideally be fixed by not more than 
one commit and the other way round, each commit should fix just one issue, 
without pulling in other changes.
   [ ] Each commit in the pull request should have a meaningful and properly 
spelled subject line and body. Copying the title of the associated issue is 
typically enough. Please include the issue number in the commit message 
prefixed by #.
   [ ] The pull request description should explain what the pull request does, 
how, and why. If the info is available in the associated issue or some other 
external document, a link is enough.
   [ ] Phrases like Fix #<issueNumber> or Fixes #<issueNumber> will auto-close 
the named issue upon merging the pull request. Using them is typically a good 
idea.
   [ ] Please run mvn process-resources -Pformat (and amend the changes if 
necessary) before sending the pull request.
