Refine database.yml template

There should be two configuration options for database.yml. Either
configuring with attributes or configuring with data bags this makes
those two choices a bit more clear and prevents a bug that causes the
chef run to fail when the database databag attribute isn't defined.

add rake db:seed to deploy resource

This adds the rake db:seed command to the deploy resource to ensure
the database gets populated with the ICLA/CCLA. This is done during
the deployment after restart, as the database will be set up, and we
want to ensure that this happens. The rake task itself is idempotent,
so re-running it should have no side effects on the database.

This also ensures the proper version of postgresql is used based on
the platform. Due to path locations, the `db:migrate` and `db:seed`
commands were failing at different points. This adds an attribute for
the postgres version. By default it will be 9.1, and can be changed by
the end user if necessary.

First stab at making this cookbook multi platform

I know it’s a big PR, but I tested it quite good on both Ubuntu 14.04
and CentOS 6.5 on both of which it now works great… So I hope this can
be merged asap and improvements/fixes can be based on this updated
multi platform code instead of the current Ubuntu only version…
Manually rebased and tested everything afterwards

All changes should be inline with master now…
