Performance issue in parallel file metadata call invokes

When concurrent connections are made to file metadata fetch api, response time grows exponentially

`
for (int i = 0; i < 20; i++) {

Thread t = new Thread(new Runnable() {

@Override

public void run() {

long tstartTime = System.currentTimeMillis();

FileMetadataResponse fileResourceMetadata = client.getFileResourceMetadata(FetchResourceMetadataRequest.newBuilder()
.setResourceId("remote-ssh-resource2")

.setResourceType("SCP")

.setResourceToken("local-ssh-cred")

.setTargetAgentId("agent0")

.build());

long tendTime = System.currentTimeMillis();

System.out.println("Thread " + Thread.currentThread().getName() + " Time " + (tendTime - tstartTime));

}

}, i + "");

t.start();

}
`

Start with the Java reproduction and the client.getFileResourceMetadata call using FetchResourceMetadataRequest, then trace the file metadata fetch API path. Run the concurrent example and measure each request's response time. Done means the response time no longer grows exponentially as concurrent metadata requests increase.
