db tasks should take username and password as arguments

[balmas]

it's a little confusing to try to deploy the database -- the db:create and db:seed tasks take a :host parameter, but the rakefile has the username hardcoded, and the password comes from the database.yml

In order to use the llt deploy client tool for this I think we need to be able to pass host, username and password to the rake task.

Ok, just adding a couple of thoughts on how to implement this then:

• The task needs to write a file, probably a hidden one, which holds the username and the password. They have to be driven out of the yml file then and read in dynamically from this auto-generated file. Environmental variables might also work.
• The reason for the hardcoded username is the dump file of the database, which also comes with this username. Have to look into this - how to abstract this, or change the database user on the fly when doing the seed.

@LFDM so I guess we have the ability to seed a remote db , but not yet the ability to deploy a compiled war which references that same db in the database.yml ?
