Upgrade and Reorganize the Camel Toolbox

JIRA Ticket: https://fedora-repository.atlassian.net/browse/FCREPO-3755

Other Relevant Links (Mailing list discussion, related pull requests, etc.) This PR won't build until https://github.com/fcrepo-exts/fcrepo-camel/pull/163 is merged.
What does this Pull Request do?

1) Remove all karaf dependencies on fcrepo-camel-toolbox for services that are currently in highest demand: fcrepo,fcrepo-indexing-solr and fcrepo-indexing-triplestore. 2) Upgrade camel to use the latest camel version (3.9.0) 3) Reorganize the camel toolbox so that it can be executed as a stand-alone Java 11 jar. 4) Add support for a -c in order to configure your camel microservices.5) Add the ability to enable select services (such as Solr or triplestore indexing) via the properties file.

What's new?

It's an all new spring app that runs the old services without karaf.

How should this be tested?

Fire up Fedora 6

docker run -p8080:8080 -p61616:61616  -p8181:8181 --name=my_fcrepo6  fcrepo/fcrepo:6.0.0

Fire up SOLR (you can use docker)

docker run  -p 8983:8983 --name my_solr solr:8

Create collection1

docker exec -it my_solr solr create_core -c collection1

Fire up fuseki

docker run --rm -p 3030:3030 --name my_fuseki atomgraph/fuseki --mem /test

Build camel toolbox

mvn clean install

Create property file using properties specified in root README of this PR. fcepo-camel-toolbox.properties

solr.indexer.enabled=true
triplestore.indexer.enabled=true
triplestore.baseUrl=http://localhost:3030/test

Run the camel toolbox

java -jar fcrepo-camel-toolbox-app/target/ fcrepo-camel-toolbox-app-6.0.0-SNAPSHOT-driver.jar -c fcrepo-camel-toolbox.properties

Add a resource to fedora. Verify that you can see updates to solr and fuseki

open "http://localhost:8983/solr/#/collection1/query?q=*:*&q.op=OR" in a browser
open "http://localhost:3030/test/query?query=SELECT%20%2A%20WHERE%20%7B%20%3Fs%20%3Fo%20%3Fp%20.%20%7D" - the query param SELECT * WHERE { ?s ?o ?p . } urlencoded.
Delete all the fedora resources and verify that all the solr and fuseki entries are gone.
Stop camel toolbox and then create a bunch of resources.
Turn camel toolbox back on

Run the reindexer and verify that fuseki and solr entries have been repopulated

curl -v -XPOST localhost:9080/reindexing -H"Content-Type: application/json" -d '["broker:queue:solr.reindex", "broker:queue:triplestore.reindex"]'
