Update Jenkins node labels to match AdoptOpenJDK label schema

[AdamBrousseau]

Ref adoptium/infrastructure#93

Since we will be reusing Adopt test JenkinsFiles (#1450), it would be a good idea to have the same node labelling schema. We should only add the labels we need.

We could also use NodeHelper API and NodeLabel job

• Add new labels to nodes
• Pull Request to update the labels for our existing build & test pipelines Update machine labels to standard schema #2204
• Remove old labels from nodes

Labels to add

zLinux

• hw.arch.s390x
• sw.os.linux
• sw.os.ubuntu
• sw.os.ubuntu.16

pLinux

• hw.arch.ppc64le
• sw.os.linux
• sw.os.ubuntu
• sw.os.ubuntu.16

aix

• hw.arch.ppc64
• sw.os.aix
• sw.os.aix.7_2

@llxia can you confirm which os label you want/prefer for test.
i.e. sw.os.linux or sw.os.ubuntu or sw.os.ubuntu.16

Talked with Adam, we should use the same labeling across sites and we can use Shubham's tool to label machine automatically.

[llxia]

As we use Jenkins files from AdoptOpenJDK for test and both sites have different labeling schema, we pass in LABEL as parameter for now.
For example:
https://ci.eclipse.org/openj9/view/Test/job/Test-Sanity-Functional-JDK8-linux_390-64_cmprssptrs/

[AdamBrousseau]

@llxia I have updated the machines with the new labels

[llxia]

Please note that test jobs are using the passed in LABEL parameter. If the label is changed, please update the default value in the test jobs.

For example:
https://ci.eclipse.org/openj9/view/Test/job/Test-sanity.functional-JDK10-aix_ppc-64_cmprssptrs/configure

Once the labels are in sync between OpenJ9 and AdoptOpenJDK, we should not need LABEL parameter any more.

Waiting on adoptium/aqa-tests#481 before I remove the old labels

[smlambert]

adoptium/aqa-tests#481 has been merged

[AdamBrousseau]

This is now complete. Thanks @smlambert and @llxia for helping drive this at Adopt

[llxia]

Updated all test jobs to set default value for LABEL to be empty ( LABEL option is kept just in case we need it for debugging). All test jobs will use the LABEL value from the AdoptOpenJDK test script.
