Change polling interval for AQA_Test_Pipeline remote triggered status

[smlambert]

At the moment, when we remote trigger test jobs from AQA_Test_Pipeline on a separate server, and want to retrieve status, we are polling every 10 seconds, which is overkill. We can switch it to every 10-20 min 4 min (as per adoptium/ci-jenkins-pipelines#1360) which will reduce the size of console output and less queries to remote server.

https://github.com/adoptium/aqa-tests/blob/master/buildenv/jenkins/aqaTestPipeline.groovy#L348-L375

The polling interval for remote triggered jobs from the build pipeline is already changed to every 20 min (via this PR: adoptium/ci-jenkins-pipelines#1240).

pollInterval : int (optional)
Polling Interval
The plugin identifies the status of the remote build by polling. Here you can specify how often the plugin shall poll the remote status.
Be aware that polling too often might cause an increased load on the remote Jenkins.

mandatory: no
default: 10

So we need to add pollInterval param to

aqa-tests/buildenv/jenkins/aqaTestPipeline.groovy

Line 350 in 6ae53a7

blockBuildUntilComplete: true,

time in seconds, suggest 4mins (240 seconds)

Note: from looking at the plugin code, it's possible for the plugin to override this initially with a value of 30seconds during initial "trigger"/"queue" state.
