Refactor to make code usable as a Python module

[mittsh]

We should be able to use db-s3-backup from a Python script with an interface that looks like:

from db_s3_backup import backup

b = backup(config_file)
b.backup()         # to backup locally and push
b.backup_local()   # to backup locally only
b.backup_remote()  # to backup in a tmp file, push and delete the file

or

from db_s3_backup import backup

b = backup(backup_directory)

# configure manually the database
b.configure_database(database_config_dictionary)

# configure manually AWS
b.configure_aws(aws_config_dictionary)

b.backup()

really like this. it shouldn't be difficult to make an API like this available. have you spent any more time on this module, @mittsh?

[pezon]

a good API method would be to push any file descriptor whats so ever, so a user may be able to construct their own serialized backups, i.e., mongo collections.

[mittsh]

@pezon absolutely, it would be nice to have at least 2 levels of controls:

• an almost automatic one, that handles all file writing and stuff
• a low lever one, where you can pass fds
  Though, not sure if it's worth it. As you mentioned in Leverage bakthat library #7 there's bakthat, it may do the same job almost.
