[Bug] Heap Dump failure due to long operation execution time

[andrewazores]

Current Behavior

See #1130

cryostat/src/main/java/io/cryostat/diagnostic/DiagnosticsHelper.java

Line 135 in 5e4a637

targetConnectionManager.executeConnectedTask(

cryostat/src/main/java/io/cryostat/targets/TargetConnectionManager.java

Line 201 in 5e4a637

public <T> T executeConnectedTask(Target target, ConnectedTask<T> task) {

The heap dump operation calls into the TargetConnectionManager using the default "failed connection" timeout duration, which is 30 seconds. This is not enough time for realistic heap dumps to be taken, since dumping the heap itself within the target JVM will take some time, and then the dumped file needs to be sent over the network to Cryostat and from there piped into storage. Completing all of these slow tasks within 30 seconds is unlikely in a real scenario.
