As page expands, the executor number column within the Build Executor Status table expands. By giving a definitive width, column will remain fixed when the page expands. If the executor# is > 99, the column can still expand due to   middle column remaining a flexible width.

Introduced Run.StatusSummarizer extension point so that Run need not refer directly to AbstractTestResultAction.

Note that this will temporarily cause double display in MavenModuleSet and similar,
until these are fixed to depend on 1.575+ and not do custom display.

Deprecating getTestResultAction as an unwanted link from the model package to hudson.tasks.test package.

This is simpler: we do not need to inspect the configuration of the project.

Moved configuration of keepDependencies into AbstractProject/configure-common.jelly, since it is not a property of Fingerprinter.

Permit RunnerStack.peek to return null in case it is not in use (for example, from a workflow), so that we do not get an NPE when trying to run a task that asks for checkpoints.
