[remote_access] Do not convert string to array when shell=True.

cros_build_lib.RunCommand requires shell=True when cmd is of type
string, otherwise the following exception is thrown:
line 556, in RunCommand
      raise Exception('Cannot run a string command without a shell')

So ssh_cmd must be of type string when cmd is of type string and shell=True. Otherwise
the following exception is thrown:
line 560, in RunCommand
    raise Exception('Cannot run an array command with a shell')

[cros_vm]: Options to run unittests on cros VM.

Support new options:
--cmd: Run a command instead of a test.
--cwd: working directory.
--files: list of files to copy over to VM.
--files-from: list of files specified in a text file to copy over.

Use case looks something like this:
Build unittests in out/Release/

To run unittests in the VM, use this command:
cros_run_vm_test --no-display --files out/Release --cwd out/Release
--cmd -- ./unittest --unittest_args

--no-display correctly gets routed to VM, and opts.args contains ['--',
'./unittest', '--unittest_args'].

We verify that:
1. --cmd always has at least 2 args ('--', and something else),
2. whenever args has something, --cmd has been specified, and,
3. that '--' is always the first arg.
