Update maven-{deploy,install}-plugin to 3.1.1

Update maven-{deploy,install}-plugin to 3.1.1

There two plugin share expectations, so their major version needs to be
bumped at the same time.

maven-deploy-plugin:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317228&version=12330476
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317228&version=12344166
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317228&version=12351654
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317228&version=12352181
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317228&version=12352894

maven-install-plugin:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317524&version=12334343
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317524&version=12344165
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317524&version=12352096
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317524&version=12352107
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12317524&version=12353026

Since single-feature-parent's mechanics results in what is considered an
incomplete project, https://issues.apache.org/jira/browse/MINSTALL-151,
set allowIncompleteProjects=true for those features. The same affects
feature-repo-parent.
