Add Camel AS2 Modules as Quarkus Extension #1471

[JiriOndrusek]

Closes #1471

As a part of the solution extension-support/bouncycastle was created. Bouncy castle security provider is required for camel-as2 and without proper initialization there are no digests working with quarkus in native.

Replaces #1488

[ ] 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 # or Fixes # 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.
[ ] Contributor guide is your good friend: https://camel.apache.org/camel-quarkus/latest/contributor-guide.html

Should pass the CI. But it fails with:
Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:exec (antora-xref-check) on project camel-quarkus-docs: Command execution failed.: Process exited with an error: 1 (Exit value: 1)

@jamesnetherton , @ppalaga do you know, what could be wrong? (Local build is working correctly and generated docs seems to be correct)

[ppalaga]

I think the failure is caused by the fact that you have some stale files in docs that were produced by the old version of the tooling (that we upgraded recently) and the new version of the tooling does not like them. So please try the following:

• Remove all files your PR has added to docs module
• Rebuild the whole tree mvn clean install -DskipTests -Denforcer.skip -Dquarkus.build.skip

• Remove all files your PR has added to docs module

Esp. this one docs/modules/ROOT/pages/extensions/as2.adoc

Thanks @ppalaga. I've removed this file some time ago, but probably I've introduced it back during rebase. Current build is executed without this doc file.
IMHO it would be nice if this error could happen also locally - I'm not sure why it didn't fail during local build

[JiriOndrusek]

Good to merge from my point of view

Thanks, @JiriOndrusek !
