The generate CLI command should provide platform-appropriate quoting

[zjs]

We should include the correct quotes for the selected platform for any arguments requiring them (e.g., because they contain whitespace or other special characters).

Note that there is some complexity around properly quoting datastore names as a part of volume store arguments (see vmware/vic#6766).

[zjs]

We should not fix this for 1.3.0.

@stuclem: We should have a release not that explains this to users and refers them to the "quoting" instructions in our documentation so that they can work around the issue.
