New ovs init command

ovs init initialises the certificate authority and ovs configuration.
Previously these tasks were performed by special jobs for the package
manager. Using a plain shell script is easier to test and uncouples
the configuration of ovs from the package manager. The configuration
steps were just writing text files from templates anyway.

These changes also include removing the openssl ASN1 workaround hacks.

There is still a lot of work to do to get ovs as a deb package without
having to rely on the more advanced debian packaging features present
in the files like debian/changelog, debian/compat, debian/templates
etc. but this is a start!
