vagrant up: Write program to log output

[jkeenan]

On the host we will repeatedly be setting up VMs for either developmental or production purposes. Assuming we are using vagrant in the installation/provisioning process, it's likely that we will be calling vagrant up repeatedly for a given VM until we've thoroughly debugged the process. We need to log the output of each such call for diagnostic purposes.

Write a program which wraps around vagrant up
and logs the output to a file on the host. The output should be grepped
before written to file to remove superfluous output, then gzipped and
timestamped so that we can distinguish among invocations.

I've gotten side-tracked on this and probably won't get back to it until after we see how test-against-dev works for perl-5.29.1 around July 20 or 21.
