Fix multiple issues in recent CI changes (#1014)

There are some issues with the recent CI changes. This PR bumps
ci-perf-kit to 0.7.2, which fixes some of them, and separate issues are
created for the issue(s) that is not fixed in the PR.

* ci-perf-kit 0.7.1 allows drawing notes on the graph to show the date
where there are known CI environment changes. But it has some issues:
* Each note is by mistake plotted only once for all the graphs (which
means only one graph will have the note). In the Python script, we
should copy the note list before processing it.
* In the case that there is only one run for several notes. (e.g. we
have notes on 1101 and 1102, and we have runs on 1103 and 1104. Both
notes for 1101 and 1102 should show on the data point for 1103. The
current CI plots one note on 1103 and one note on 1104. We should
combine the notes on 1101 and 1102, and plot them for the run 1103.
* 0.7.1 sets the heap size to 8g (for OpenJDK NoGC runs, and mutator
runs), but by mistake uses a modifier `heap30g`. This causes confusion.
It should be name as `heap8g`.
* 0.7.1 by mistake sets the plan to `gencopy` in a GenImmix config.

ci-perf-kit 0.7.2
(https://github.com/mmtk/ci-perf-kit/releases/tag/0.7.2) fixes those
issues.
