Change cells.sequence_range to cells.sequence_ranges

Overview

Cells sequence range in topology service config.toml is changed to hold multiple sequence-ranges - gitlab-org/cells/topology-service!188 (merged).

To be inline with this, GDK should also update its cells config.

• To have sequence_ranges
• And assign 100 billion as default sequence_range.
