Flagsets are not necessary for initializing the web server/service.
Passing them will cause micro to call the flagset function again which
then overrides the given value with the default value.
Fixes#33
So far Phoenix have been embedded into the binary and we can customize
the required config based on flags, env variables and optionally via
config file. For now I'm embedding the whole Phonix content, optherwise
the all-in-one binary `ocis` will get pretty complicated until we add
the generate commands to that repo as well and provide a mechanism to
inject the embedding.
