/**
 * @module SecretCreateOrUpdate
 * SecretCreateOrUpdate component displays either the form for creating a new secret or creating a new version of the secret
 *
 * @example
 * ```js
 * <SecretCreateOrUpdate
 *  @mode="create"
 *  @model={{model}}
 *  @showAdvancedMode=true
 *  @modelForData={{@modelForData}}
 *  @isV2=true
 *  @secretData={{@secretData}}
 *  @canCreateSecretMetadata=false
 * />
 * ```
 * @param {string} mode - create, edit, show determines what view to display
 * @param {object} model - the route model, comes from secret-v2 ember record
 * @param {boolean} showAdvancedMode - whether or not to show the JSON editor
 * @param {object} modelForData - a class that helps track secret data, defined in secret-edit
 * @param {boolean} isV2 - whether or not KV1 or KV2
 * @param {object} secretData - class that is created in secret-edit
 * @param {boolean} canUpdateSecretMetadata - based on permissions to the /metadata/ endpoint. If user has secret update. create is not enough for metadata.
