Did you run make format && make check?

Fixes #1046 #1050 #1054 #1061

Changes:

• added --public-rpc flag to change CLIAddr from localhost:3435 to :3435.
• added comparing step on adding hypervisors keys on --hypervisor-pks <visor-pk> flag, that if key equal to visor PK, then change this visor to hypervisor.
• added --vpn-server-enable flag to make vpn-server app autostart attribute true
• improve --package flag to distinguished between hypervisor and visor, and change its config output file name
• add a checking --output or -o flag, and if set was used then override -p and -s flag

How to test this PR:

• build at this PR by make build
• generate config with ./skywire-cli config gen --public-rpc
• check for CLIAddr value, should be :3435
• add visor pk as hypervisor pks by skywire-cli config gen --hypervisor-pks <visor-pk> -ro skywire-config.json
• check config file that hypervisors should be empty [], and hypervisor config part should added to config file.
• generate/update config with ./skywire-cli config gen -r --vpn-server-enable
• check config file to confirm that vpn-server autostart is true
• generate config twice with -pi and -p to check their different name
• generate config with -pir or -sr with -o config.json flag to see override functionality

cli_addr should actually be ":3545"

I think it's equivalent to 0.0.0.0 for the ip address to be blank but the port is listed

We need consistency in the default behavior for some things.

Is enable-auth to be considered default? If so, can you make sure it is evenly implemented, it was changed to not enabled by default in the -p flag but the default when you give no arguments is enabled

and can you put a flag for the config generation to --disable-auth also, if we go with the aforementioned default?

As had conversation with Moses on matrix, we want these changes:

• disable OS detection in runtime, and set flag instead
  • as default set to linux, and can set by --os windows or --os macos flag.
• disable auth in hypervisor as default, and be enabled by -p flag, or set OS to windows or macos
• set enable-auth and disable-auth flag separately
• remove -s flag completely
• all apps be available as default, and remove each by flags
  • you should separate apps by ,, same as --disable-apps skysocks,vpn-server

Looks alright. Only need to double check we are not using the deprecated flag in Skybian still.
