Standardize on "auth method"
This removes all references I could find to:

- credential provider
- authentication backend
- authentication provider
- auth provider
- auth backend

in favor of the unified:

- auth method

Usage: vault login -method=userpass [CONFIG K=V...]
The userpass auth method allows users to authenticate using Vault's
internal user database.
If MFA is enabled, a "method" and/or "passcode" may be required depending on
the MFA method. To check which MFA is in use, run:
$ vault read auth/<mount>/mfa_config
Authenticate as "sally":
$ vault login -method=userpass username=sally
Password (will be hidden):
Authenticate as "bob":
$ vault login -method=userpass username=bob password=password
Configuration:
method=<string>
MFA method.
passcode=<string>
MFA OTP/passcode.
password=<string>
Password to use for authentication. If not provided, the CLI will prompt
for this on stdin.
username=<string>
Username to use for authentication.
