Accounts added from authentication providers should now be displayed under a new "Accounts" icon on the activity bar.

Interaction with Settings Sync

• "Sign in to Microsoft" entry should sign in, then prompt to turn on settings sync
• Signing into an additional account should show a quick pick to change accounts
• Signing out of the settings sync account should prompt to turn off settings sync

Managing trusted extensions

• When an extension first tries to login or resolve an access token using the auth provider API, a consent prompt should be shown to the user. If the user clicks allow, this extension should show up under the "Manage Trusted Extensions" list for the account
  Sample extension code:

export async function activate(context: vscode.ExtensionContext) {
  const scope = ['user:email'];
  context.subscriptions.push(vscode.commands.registerCommand(
    "github-auth.helloWorld",
    async () => {
      let token;

      const result = await vscode.authentication.getSessions("github", scope);
      if (!result.length) {
        const session = await vscode.authentication.login("github", scope);
        token = await session.getAccessToken();
      } else {
        token = await result[0].getAccessToken();
      }

      vscode.window.showInformationMessage(`Got token ${token}`);
    }
  ));
}

• If the extension is removed from the list using "Manage Trusted Extensions", the consent prompt should be shown again on all subsequent login or getAcessToken calls
