dccLogoutButton: LogoutButton component

Description

Logout button to submit a form post request to the `logout_url` prop. Usage is intended for dash-deployment-server authentication. DDS usage: `dcc.LogoutButton(logout_url=os.getenv('DASH_LOGOUT_URL'))` Custom usage: - Implement a login mechanism. - Create a flask route with a post method handler. `@app.server.route('/logout', methods=['POST'])` - The logout route should perform what's necessary for the user to logout. - If you store the session in a cookie, clear the cookie: `rep = flask.Response(); rep.set_cookie('session', '', expires=0)` - Create a logout button component and assign it the logout_url `dcc.LogoutButton(logout_url='/logout')` See https://dash.plotly.com/dash-core-components/logout_button for more documentation and examples.
