Update releaseVersion to 2.298.0

* adding support for a service container docker logs

* Adding Unit test to ContainerOperationProvider

* Adding another test to ContainerOperationProvider

* placed the docker logs output in dedicated ##group section

* Removed the exception thrown if the service container was not healthy

* Removed duplicated logging to the executionContext

* Updated the container logs sub-section message

* Print service containers only if they were healthy
Unhealthy service logs are printed in ContainerHealthCheckLogs called prior to this step.

* Removed recently added method to inspect docker logs
The method was doing the same thing as the existing DockerLogs method.

* Added execution context error
This will make a failed health check more visible in the UI without disrupting the execution of the program.

* Removing the section 'Waiting for all services to be ready'

Since nested subsections are not being displayed properly and we already need one subsection per service error.

* Update src/Runner.Worker/Container/DockerCommandManager.cs

Co-authored-by: Tingluo Huang <tingluohuang@github.com>

* Update src/Test/L0/TestHostContext.cs

Co-authored-by: Tingluo Huang <tingluohuang@github.com>

* Change the logic for printing Service Containers logs

Service container logs will be printed in the 'Start containers' section only if there is an error.
Healthy services will have their logs printed in the 'Stop Containers' section.

* Removed unused import

* Added back section group.

* Moved service containers error logs to separate group sections

* Removed the test testing the old logic flow.

* Remove unnecessary 'IsAnyUnhealthy' flag

* Remove printHello() function

* Add newline to TestHostContext

* Remove unnecessary field 'UnhealthyContainers'

* Rename boolean flag indicating service container failure

* Refactor healthcheck logic to separate method to enable unit testing.

* Remove the default value for bool variable

* Update src/Runner.Worker/ContainerOperationProvider.cs
