Jiri Stransky d61e5698c7 Customizable vagrant rsync args and excludes ...

When using rsync file synchronization with Vagrant, the whole kubernetes
repo directory is copied over into the virtual machine. This includes
the _output directory, which tends to be gigabytes in size, while often
just _output/release-tars (a few hundred MB) would be enough.

Furthermore, if the some of the directories contains a recursive
symlink, rsync with the default args will keep descending and copying
files endlessly until filling up the VM disk.

Making the rsync args and excluded dirs/files customizable via
KUBERNETES_VAGRANT_RSYNC_ARGS and KUBERNETES_VAGRANT_RSYNC_EXLUDE,
respectively, allows the developer to prevent the issues mentioned
above. A new KUBERNETES_VAGRANT_USE_RSYNC variable is also added to
control whether Vagrant should force usage of rsync as the file
synchronization backend. The args/exclude customizations only take
effect when KUBERNETES_VAGRANT_USE_RSYNC is 'true'.
