Windows ps update (#909)

* query command with json, web, xml

* query xml now working

* clippy

* comment out web tests

* Initial work on query web

For now we can query everything except tables

* Support for querying tables

Now we can query multiple tables just like before, now the only thing
missing is the test coverage

* Revert "Query plugin"

* augment `ps -l` on windows to display more info
