Do not ignore the sentinal file when running resume

The sentinal file was always being ignored when running the
resume command. This is fixed along with allowing provision
options to be used with resume. Fixes #6787

 This resumes a Vagrant managed machine that was previously suspended,
 perhaps with the [suspend command](/docs/cli/suspend.html).
+
+The configured provisioners will not run again, by default. You can force
+the provisioners to re-run by specifying the `--provision` flag.
+
+# Options
+
+* `--provision` - Force the provisioners to run.
+
+* `--provision-with x,y,z` - This will only run the given provisioners. For
+  example, if you have a `:shell` and `:chef_solo` provisioner and run
+  `vagrant provision --provision-with shell`, only the shell provisioner will
+  be run.
