Resume Workflow Execution

Start all ECs that were shut down during the upgrade.
```
$ mzsh startup <ec names>
```
Start the workflows on the restarted ECs.
Enable all workflow groups, from the Execution Manager in Desktop, or by entering the mzsh wfgroupenable command, for example:
```
$ mzsh mzadmin/<password> wfgroupenable \*
```
