A collection of all token providers. The token providers should be used when the authorization
type is going to be token based. For example, the `bearer` authorization type set using
[httpBearerAuth trait][http-bearer-auth-trait] in Smithy.

## Static Token Provider

```ts
import { fromStatic } from "@aws-sdk/token-providers"

const token = { token: "TOKEN" };
const staticTokenProvider = fromStatic(token);

cont staticToken = await staticTokenProvider(); // returns { token: "TOKEN" }
```

## SSO Token Provider

```ts
import { fromSso } from "@aws-sdk/token-providers"

// returns token from SSO token cache or ssoOidc.createToken() call.
cont ssoToken = await fromSso();
```

## Token Provider Chain

```ts
import { nodeProvider } from "@aws-sdk/token-providers"

// returns token from default providers.
cont token = await nodeProvider();
```
