Fixes: #478 Related to #2

Description of the change:

Reimplements the /api/beta/credentials/{connectUrl} endpoint. This is used on the Security > Store Credentials > List view for testing credentials against targets before actually storing the credential.

How to manually test:

1. Check out and build PR
2. ./smoktest.bash -Ot
3. Go to Security > Store Credentials
4. Enter a test credential with the match expression true and credentials admin:adminpass123
5. Click the List tab and click Test for each target
6. Verify that the credential is Valid for vertx-fib-demo targets with ports 9094 and 9095, Invalid for cryostat3:9091, and Not Applicable for all others

Before this PR, all of the results would come back with Invalid responses for everything since the endpoint would always return a 404.
