In this commit, a new channel-ID index is added to the tower client db with the help of a migration. This index holds a mapping from a db-assigned-ID (a uint64 encoded using BigSize encoding) to real channel ID (32 bytes). This mapping will help us save space in future when persisting references to channels.
