If set, 'ssh+socks5://' proxying will skip host key validation
validation of the remote ssh server.
The proxy environment variables support proxies with the schemes 'http://',
'https://', 'socks5://', or 'ssh+socks5://'. http, https, and socks5 do what they
say - they'll proxy through the server with the hostname:port given using the
protocol specified in the scheme.
'ssh+socks5://' will open an SSH tunnel to the given server, then will start a
local SOCKS5 proxy temporarily which sends its traffic through the SSH tunnel.
Because this requires an SSH connection, some extra information is required.
This type of proxy should be specified in the form
ssh+socks5://<user>@<hostname>:<port>/<path-to-private-key>
or ssh+socks5://<user>@<hostname>:<port>?private-key=<path-to-private-key

Summary: "Initialize a new vault",
Usage: "safe init [--keys #] [--threshold #] [--single] [--json] [--no-mount] [--sealed]",
Description: `
Initializes a brand new Vault backend, generating new seal keys, and an
initial root token. This information will be printed out, so that you
can save it somewhere secure (encrypted drive, password manager, etc.)
By default, Vault is initialized with 5 unseal keys, 3 of which are
required to unseal the Vault after a restart. You can adjust this via
the --keys and --threshold options. The --single option is a shortcut
for specifying a single key and a threshold of 1.
Once the Vault is initialized, safe will unseal it automatically, using
the newly minted seal keys, unless you pass it the --sealed option.
The root token will also be stored in the ~/.saferc file, saving you the
trouble of calling 'safe auth token' yourself.
The --json flag causes 'safe init' to print out the seal keys and initial
root token in a machine-friendly JSON format, that looks like this:
