add reading of 'seedfrom' via DataSourceNoCloud's DataSourceConfig
What this does is provide an second DataSource that could use the
kernel command line url=. For example:
ro root=/dev/vda url=http://example.com/i-abcdefg/
http://example.com/i-abcdefg/ would contain:
datasource:
NoCloud:
# default seedfrom is None
# if found, then it should contain a url with:
# <url>/user-data and <url>/meta-data
# seedfrom: http://my.example.com/i-abcde
seedfrom: http://example.com/i-abcdefg/
Then, the NoCloudNet DataSource would find that seedfrom config
and consume data at
http://example.com/i-abcdefg/user-data
and
http://example.com/i-abcdefg/meta-data
