Add rotating token support for admin API (#9244)

Use the *credentials.Credentials implementation method *Get*

```
func (c *Credentials) Get() (Value, error) {
```

which also handles auto-refresh, this allows for chaining
of various implementations together if necessary or simply
initialize with credentials.NewStaticV4(access, secret, token)
