rptest: add addressing style configuration to ducktape

The addressing style used by `redpanda` for ducktape tests can now
be set with the variable `cloud_storage_url_style` in `SISettings`,
or injected into a test similar to `cloud_storage_type` with a decorator.

e.g: `@matrix(cloud_storage_url_style=['path','virtual_host'])`
