#3370 smf: ProcExecLevel is not correct in Balanced In Service Upgrade (BISU)

[Thang Duc Nguyen]

The cluster size is 10 (2 SCs and 8 PLs).
The upgrade is configured to run with BISU: numberOfSingleSteps 4.
There are 2 original procedures, the proc0 (ExecLevel 0) will do rolling upgrade SCs and proc1 (ExecLevel 1) will do rolling on PLs.
After BISU configured, there are 4 Balanced procs created corresponding with ExecLevel 2, 3, 8, 9. This is incorrect. Their ExecLevel should be 2, 3, 4, 5.

smfd: Correct exec level of balanced procedure [#3370]

When the upgrade is configured as balanced in service upgrade (BISU),
the exec level of balanced proc is set to one higher than the highest
of the original proc used in balanced groups. The exec level
of balanced procedures should not be set by another balanced procs.
