ha: Fix race on creation of drbd resources

The drbd OCF resource agent expects the drbd primitive and the drbd ms
resource to be created in the same transaction. When it doesn't, then
the drbd primitve will fail to be monitored, which can lead to fencing.

We didn't see that all the time because we create the ms resource fast,
so most of the time, it just works.

set the postgresql node attributes manually

Crowbar (esp. migrations) doesn't allow us to have custom namespaces at
the same level as the current cookbook. So we need to hack this in the
recipe.

move max_connections to postgresql.config

Since we're not using the config_pgtune postgresql recipe, the
max_connections attribute never got used. We need to move it under
node['postgresql']['config'] in order for the postgresql.conf template
to pick it up.
set log attributes in the databags rather than the model

Move log settings from the crowbar app model to the data bag since they
don't ever get updated.
