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

+# Alerts
+An alert is an inline message that contains a short description that a user cannot manually dismiss. With exception to the error message on the login page, alerts are not triggered by user action. Success and error notifications based on user actions are created using a toast component.
