Add alert message component and documentation

- Add custom alert component to simplify the use of custom alerts
- Add documentation for using the custom alert
- Update the login error alert to use the alert component instead of
the Bootstrap-vue component.
- Add the enhanceApp and bmcAppPlugin to extend vuepress to use both
the BMC custom and Boostrap-Vue components along with the custom styles
