support conventional domain name with one or more dot

[wind dong]

This is not a bug but a proposal.
Formal domain name will have one or more dot within the name, meantime, it's common for one company own several domains, for example abc.com and abc.net. If keystone with multi-domain support only supports domain name without '.', users will have to use abc_com and/or abc_net instead, which is not as good as to use abc.com and/or abc.net.
I made below little change to support conventional domain name use in /etc/keystone/domains/keystone.abc.com.conf and/or /etc/keystone/domains/keystone.abc.net.conf.

    support conventional domain name with one or more dot

    Formal domain name will have one or more dot within the name,
    meantime, it's common for one company own several domains,
    for example abc.com and abc.net. But currently keystone
    multi-domain support only supports domain name without '.',
    because the wrong way that get the domain name from domain
    config file name.
