The labs env can be anything starting by 'labs', such as
'labs-logistics', 'labs-finance', ...
* At install, s3/swift is set as default storage
* However, unlike prod/integration, the storage is not forced to be an
object storage
* Redis is required
* When the storage is set on s3/swift, then the bucket name is mandatory
(otherwise, there is no place where to create the files...)
The redis prefix regex match is relaxed: anything starting by a project
name, then '-odoo-', then any combination of letters, digits, and dashes
is accepted (so a prefix my-project9-odoo-labs-web3 is valid).
