[FEATURE REQUEST] win_pkg.py print debug logging of full command being run

[dafyddj]

Is your feature request related to a problem? Please describe.

When working with Windows software installers using winrepo it would be a great timesaver to know exactly what command Salt is running.
Currently the only information given is:
[INFO ] Executing command '"C:\Windows\system32\cmd.exe"' in directory 'C:\ProgramData\Salt Project\Salt\var\ca lt\minion\extrn_files\base\the.earth.li\~sgtatham\putty\0.77\w64'
which is useless for the purpose of developing a new winrepo package definition.

Describe the solution you'd like

I would like a log message such as:
[DEBUG] Executing '"msiexec" /I "C:\\ProgramData\\Salt Project\\Salt\\var\\cache\\salt\\minion\\extrn_files\\base\\the.earth.li\\~sg \\putty\\0.77\\w64\\putty-64bit-0.77-installer.msi" ALLUSERS=1 /qn'

Describe alternatives you've considered

An alternative is to break out the debugger to check on the cmd_shell and arguments variables at the point the command is run. The requested debug logging would save a lot of time.

I have looked at the options available in cmd.run_all and it doesn't look like an option exists to log the full cmd and arguments prior to running.
