Add-CloudServer allows zero to five files to be copied to new server

Using the "Personality" feature of the OpenStack API, the Add-CloudServer command now allows zero to five files to be specified when creating a server. Add-CloudServer will limit the number of files from zero to five.

File loading is done by using the -File parameter, with file names being separated by commas, such as the following:

-File "C:\\cloud-automation\\bootstrap.cmd=C:\bootstrap.cmd", "C:\\cloud-automation\\bootstrap2.cmd=C:\bootstrap2.cmd"
