Description

Remove old Grid tests since features exist in current Grid

Motivation and Context

LoadBalancedTest
Feature: Incoming test should be load-balanced among all the Nodes in the Grid

Details:
In Grid 4 the Distributor identifies the Node for new incoming session request. This Node selection is done here: https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/distributor/selector/DefaultSlotSelectorTest.java
While selecting the Node, the Node’s load is also considered.
Test: https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/distributor/DistributorTest.java#L496

NewRequestCrashesDuringNewSessionTest
Feature: New session creation error should not lead to an inconsistent state in the Grid

Details:
If any error happens while creating a new session request, the error is propagated back to the Distributor and depending on the error, the request is either retried or rejected. In case the request is retried, it will be retried up to a certain timelimit then rejected. Similarly, if the request sits in the new session request queue and the Grid is facing any issue in polling the session, the timed-out requests are removed from the queue.

Tests:
https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/router/SessionQueueGridTest.java
https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/router/NewSessionCreationTest.java#L158

RemoteProxySlowSetup
Feature: Multiple time if the same node is registered, then it is counted as one.

Grid 3 :
Any new incoming node registers itself with the Hub. If two same nodes (same configuration) register to the Hub, only one node registers itself.

Grid 4 :
Same as Grid 3

Test:
https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/distributor/DistributorTest.java#L480

SessionTimesoutTest
Feature: Remove any inactive session after a configured time period. Poll all nodes at regular intervals (configurable) and remove inactive Nodes.

Grid 3 :
timeout - Configurable flag for removing inactive session. If the session is inactive for more than that time, the session is removed from the Grid and frees up the slot.
cleanUpCycle - Hub polls all the Node at regular interval and removes inactive Node.

Grid 4 :
Same as Grid 3
session - timeout - Configurable flag for removing inactive session. If the session is inactive for more than that time, the session is removed from the Grid and frees up the slot.
heartBeat-period - Hub polls all the Node at regular interval and removes inactive Node.

SmokeTest

Grid 3 :
Test to check end to end functionality of the Grid for 10 tests.

Grid 4 :
Covered in
https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/router/EndToEndTest.java

https://github.com/SeleniumHQ/selenium/blob/trunk/java/server/test/org/openqa/selenium/grid/router/StressTest.java

Since the features described above are present in Grid 4. It is safe to remove the tests.
