new flag --confpath on generate config

[mrpalide]

Did you run make format && make check? Yes

Fixes #_

Changes:

• add --confpath flag as path of offline file of https://conf.skywire.skycoin.com service that could read from file instead server for times that conf service not available.

How to test this PR:

• build binaries
• save https://conf.skywire.skycoin.com data into file like conf.json
• trying to create config by skywire-cli config gen --confpath path/to/conf.json command

could the same --conf or -a flag be used, and simply check if the string provided is a local file or a url? And perhaps change the help text to say specify service conf url or file?

simply check if the string provided is a local file or a url?

It's just about offline file of config bootstrapper service. May I add custom-url too @0pcom ?

we already have it as config gen -a

the long flag might be --url but you can change that to --conf or something like that

Unfortunately, no straightforward method for validate URL. Check here https://stackoverflow.com/a/55328193.
So we keep separate flags for URL and file of service conf.
