debug-log on windows clouds not tailing

[Matthew Williams]

Running juju debug-log from a linux client to a windows server on azure doesn't appear to always tail the log properly.

For example I run juju debug-log and wait. Last output is

unit-mssql-express-2: 12:25:11 DEBUG juju.worker.logger logger setup

Then I Ctrl+C and run juju debug-log again and now I see updated log messages:
unit-mssql-express-2: 13:00:54 ERROR unit.mssql-express/2.juju-log Error while running C:\Juju\lib\juju\agents\unit-mssql-express-2\charm\hooks\install.ps1
unit-mssql-express-2: 13:00:54 ERROR unit.mssql-express/2.juju-log MSSQL Express 2014 failed to install

Juju no longer supports Windows machines, so marking as invalid.
