storage_domain is inconsistent between cname_lookup and domain_remap

[Romain LE DISEZ]

On middleware cname_lookup, storage_domain is a list of valid domains for the Swift cluster.

On middleware domain_remap, storage_domain is a single valid domain for the Swift cluster.

It seems inconsistent. If an operator is using multiple domains for cname_lookup, it is highly probable that it will want to use multiple domains with domain_remap.

domain_remap should accept a list of domains in storage_domain parameter.

    Accept storage_domain as a list in domain_remap

    Middleware domain_remap can work with cname_lookup middleware. This last
    middleware accept that storage_domain is a list of domains. To be
    consistent, domain_remap should have the same behavior.
