CE-3625: Migrate auth components

• D&M is the only app using AccessControl and it was using a local version not this from ess-common. I found another way to restrict access in D&M that I think is a good solution and therefor deleted AccessControl component all together. We'll see what you think.
• Renamed userContext to AuthContext since it handles more than just the user info.
• This also contains some fixes for comments on previous MR.
• I have a draft MR for D&M which can be used to test

src/contexts/AuthContext.ts

+import { createContext, useContext } from "react";
+
+export interface User {
+  fullName?: string;
+  loginName?: string;
+  avatar?: string;
+  email?: string;
+  gitlabUserName?: string;
+}
+
+export interface AuthContextProps {
+  user: User | undefined;
+  userRoles: string[] | undefined;
+  isAdmin: boolean | undefined;
+  isManager: boolean;
+  loginError: string | undefined;
+  loginLoading: boolean;
+  login: (userName: string, password: string) => void;
+  logout: () => void;
+  resetLoginError: () => void;
+}
+
+const defaultValue: AuthContextProps = {
+  user: undefined,
+  userRoles: undefined,
+  isAdmin: false,
+  isManager: false,
+  loginError: undefined,
+  loginLoading: false,
+  login: () => {},
+  logout: () => {},
+  resetLoginError: () => {}
+};
+
+export const AuthContext = createContext<AuthContextProps>(defaultValue);
+
+export const useUserContext = () => {
+  const {
+    user,
+    userRoles,
+    isAdmin,
+    isManager,
+    loginError,
+    loginLoading,
+    login,
+    logout,
+    resetLoginError
+  } = useContext(AuthContext);
+
+  return {
+    user,
+    userRoles,
+    isAdmin,
+    isManager,
+    loginError,
+    loginLoading,
+    login,
+    logout,
+    resetLoginError
+  };
+};
