/**
 * @module GenerateCredentialsDatabase
 * GenerateCredentialsDatabase component is used on the credentials route for the Database metrics.
 * The component assumes that you will need to make an ajax request using queryRecord to return a model for the component that has username, password, leaseId and leaseDuration
 *
 * @example
 * ```js
 * <GenerateCredentialsDatabase @backendPath="database" @backendType="database" @roleName="my-role"/>
 * ```
 * @param {string} backendPath - the secret backend name.  This is used in the breadcrumb.
 * @param {object} backendType - the secret type.  Expected to be database.
 * @param {string} roleName - the id of the credential returning.
