There's a bug in Undertow that means it may leak a file handle is
the server is stopped immediately after a response to an SSL request
has been received. The stop processing races with Undertow's SSL
support tidying things up after sending the response. When the stop
processing wins, the tidying up fails with a NullPointerException that
prevents an input stream from being closed. On Windows, the input
stream remaining open prevents JUnit from being able to clean up its
temporary directory.

This commit uses Awaitility to wait for the file that's being served
over SSL to be deleted before stopping the server. On Windows, this
will delay the stop processing from beginning until after the tidy up
that's performed after sending the response has been completed,
hopefully eliminating the race condition that resulted in the input
stream being left open.

Update `EndpointDiscoverer` so that `@Endpoint` and `@EndpointExtension`
beans are created as late as possible.

Prior to this commit, endpoint beans and extension beans would be
created during the discovery phase which could cause early bean
initialization. The problem was especially nasty when using an embedded
servlet container since `ServletEndpointRegistrar` is loaded as the
container is initialized. This would trigger discovery and load all
endpoint beans, including the health endpoint, and all health indicator
beans.
