Take a token as secret in a dialog instead of taking it directly as a CLI argument

__Proposal:__

Prepare new command "influx config set-token" to pass the token in a secret dialog.

__Current behavior:__

It takes the token from CLI argument.

__Desired behavior:__

`influx config set-token` can set a token with a secret dialog.
If `influx config create` is called with `--set-token`, it takes token with a secret dialog.

__Use case:__
CLI options are openly exposed on the shell.
So we have to be careful not to leave tokens in the shell's history, etc.
This is a flaw that cannot be ignored for security reasons.

Start by locating the implementations of `influx config set-token` and `influx config create --set-token`; no file or test is named in the issue. Confirm how each currently receives the token, then verify that the token is entered through a secret dialog and is no longer exposed as a CLI argument.
