Adds a new `rsync__rsync_ownership` option to rsync based synced folders
which will allow rsync to use the `--chown` flag if it is available. The
`rsync` and `rsync-auto` commands have a new `--rsync-chown` flag which
can be used to force the option on folders when running the commands.
Fixes#7329#7332
Rescue and re-wrap any errors encountered when running the post
rsync capability. Rescue this exception type and notify of error
when encountered by rsync auto. Include test coverage.
Include config option within ssh_config command output template. Default
remote_user value to set username value. Include existence check on
provided config value to ensure file is available. Update tests to
include coverage on all changes. Add new options to the docs.
Prior to this commit, when creating the ControlPath tmp dir for
socket path, Vagrant would simply rely on `rand(1000)` for making unique
dirs for rsyncing files which could result in collisions. This commit
updates that be properly using `Dir.mktmpdir` with a `vagrant-rsync-`
prefix.
As of `net-ssh` version 4.2.0, the key :paranoid has been deprecated in
favor of using :verify_host_key. This commit updates Vagrants ssh config
to use the new key, and deprecates the use of :paranoid.
