automation: execute powershell when connecting

For some reason, the ability to execute PS scripts appears to
come online after the ability to execute regular command scripts.
This is creating race conditions when connecting to instances
resulting in our wait_for_winrm() returning before PS is available
leading to an exception being thrown in other code.

Let's change the client connection code to execute a minimal
PS script so we can try to trap the exception in wait_for_winrm().

test that we don't interrupt the merge session if
a file-level merge failed

  $ hg init repo
  $ cd repo

  $ echo foo > foo
  $ echo a > bar
  $ hg ci -Am 'add foo'
  adding bar
  adding foo

  $ hg mv foo baz
  $ echo b >> bar
  $ echo quux > quux1
  $ hg ci -Am 'mv foo baz'
  adding quux1

  $ hg up -qC 0
  $ echo >> foo
  $ echo c >> bar
  $ echo quux > quux2
  $ hg ci -Am 'change foo'
  adding quux2
  created new head

test with the rename on the remote side
  $ HGMERGE=false hg merge

  merging foo and baz to baz
  merging bar failed!
