This is a variant about quotactl01.c and used to test project quota.
I split it into a new case instead of adding it in quotaclt01.c because
two points:
1)Before linux 4.10, ext4 doesn't support project quota.
2)On old kernel, kernel doesn't permit mount both prjquota and grpquota together.

+ *
+ * 1) quotactl(2) succeeds to turn on quota with Q_QUOTAON flag for project.
+ * 2) quotactl(2) succeeds to set disk quota limits with Q_SETQUOTA flag
+ * for project.
+ * 3) quotactl(2) succeeds to get disk quota limits with Q_GETQUOTA flag
+ * for project.
+ * 4) quotactl(2) succeeds to set information about quotafile with Q_SETINFO
+ * flag for project.
+ * 5) quotactl(2) succeeds to get information about quotafile with Q_GETINFO
+ * flag for project.
+ * 6) quotactl(2) succeeds to get quota format with Q_GETFMT flag for project.
+ * 7) quotactl(2) succeeds to get disk quota limit greater than or equal to
+ * ID with Q_GETNEXTQUOTA flag for project.
+ * 8) quotactl(2) succeeds to turn off quota with Q_QUOTAOFF flag for project.
