winrm parallel execution failure

[mfrg]

Describe the bug

There is a bug in the winrm connector that manifests itself sometimes depending on the facts/ops running when run in parallel with multiple hosts. This does not happen with --serial so it's something to do with parallel execution.

The ultimate exception raised is from ntlm_auth -- "The signature checksum does not match, message has been altered"

This is not on all parallel runs, only when a certain op/fact is triggered across amongst the host set. I will try getting a better repro in the next few days and figure out what is happening.

To Reproduce

No generic repro yet.

Expected behavior

The parallel execution works the same as serial.
