Addition of RedirectPath as a parameter to init

[priyarath9]

We can add a new RedirectPath parameter to the init method, where the new parameter can be appended to the redirect URL for the app id instance.

await appID.init({
    clientId: '<SPA_CLIENT_ID>',
    discoveryEndpoint: '<WELL_KNOWN_ENDPOINT>',
    redirectPath: '<Redirect_Path>'
});

await this.openIdConfigResource.init({discoveryEndpoint, requestHandler: this.request});
this.redirectPath = redirectPath;
		this.popup.init(popup);

let origin = this.window.location.origin;
		if (!origin) {
			origin = this.window.location.protocol + "//" + this.window.location.hostname + (this.window.location.port ? ':' + this.window.location.port : '');
		}
if (this.redirectPath && this.redirectPath != '') {
    origin = origin + this.redirectPath;
}

@priyarath9 can you, please, provide some examples of how adding the redirectPath would be useful?
