MAAS: improve the main of datasource to look at kernel cmdline config.

This just looks in one other maas related path for a config file.
The file '91_kernel_cmdline_url' is written by cloud-init when it
gets a cloud-config-url parameter.

Also now we read the config even if a url is specified to potentially
fill in credentials.
