Add display attributes for OpenAPI OperationID's

[averche]

Overview

The display attributes added in this PR will be translated into OperationID's in vault-generated OpenAPI documents (when calling /sys/internal/specs/openapi with this plugin enabled). The OperationID's will, in turn, be translated into function / method names in generated OpenAPI-based libraries (e.g. hashicorp/vault-client-go & hashicorp/vault-client-dotnet).

---

This PR will introduce the following OperationIDs:

Path	Method	OperationID
"/auth/{kubernetes_mount_path}/config"	"get"	"kubernetes-read-auth-configuration"
"/auth/{kubernetes_mount_path}/config"	"post"	"kubernetes-configure-auth"
"/auth/{kubernetes_mount_path}/login"	"post"	"kubernetes-login"
"/auth/{kubernetes_mount_path}/role"	"get"	"kubernetes-list-auth-roles"
"/auth/{kubernetes_mount_path}/role/{name}"	"get"	"kubernetes-read-auth-role"
"/auth/{kubernetes_mount_path}/role/{name}"	"post"	"kubernetes-write-auth-role"
"/auth/{kubernetes_mount_path}/role/{name}"	"delete"	"kubernetes-delete-auth-role"
