Default values for capacity and price will be 0, so storage node
won't be present in placement. Add these attributes if they are
not explicitly set up by user config.

Well-known attributes set up with explicit configuration
values, other attributes set up from chain of attributes.
Chain of attributes is a string, that contains keys-value pairs,
divided by semicolon. Pairs itself divided by slash.
E.g. "StorageType:HDD/RPM:7200"

To run storage node at dev-env environment it should have
configurable parameters. To keep `cfg` structures we can
read configuration from env and yml config file with viper
and parse values such as script hashes, fees, keys into
`cfg` structures.
