Missing `readTotalSecs` metric at  Monit
**Impact of the bug**
Monitoring 

**Describe the bug**
It was reported by the Monitoring Team that we fail to upload some metrics from the Frame work job report to monit. And the eventual reason we've been pointed to, must be a typo in the following line at the FwkJobReport XMLParser: https://github.com/dmwm/WMCore/blob/02f70c36892c146546a7eeec5d3e4fda4b278682/src/python/WMCore/FwkJobReport/XMLParser.py#L458 

i.e.  `totalMSecs` should be changed to `totalMsecs` (lower case `s`).

**How to reproduce it**
Try to parse a CMSRun XMl output with the current parser.

**Expected behavior**
The parser not to miss  a field.

**Additional context and error message**
This bug was found in the context of preparing better `CPUEfficiency` plots:
