Added two commands to dump snapshot config
and provide it for snapshot task
Will download default config and dump it to stdout
fuel snapshot --conf > conf.yaml
Next command will accept config as input and bypass it to snapshot
generation request
fuel snapshot < conf.yaml
This is required to overwrite certain parameters if needed,
some of those are:
- target directory of snapshot generation
- timeout of snapshot generation procedure
- exclusion/inclusion of certain directories
