PREview update for improved stability

[benr]

Description

This PR is aimed at improving the stability of the PREview system used for creating ephemeral preview environments to improve the development experience. Specifically it:

1. Creates a checksum from the branch name which becomes the name of the bucket (and thus PREview URL), which avoid problems with characters that are allowed in branch names but not in bucket names
2. Reduces duplication of the bucket name generation scheme
