[SDK-3548] Introduce authorizationParams to hold properties sent to Auth0

[ewanharris]

Changes

Moves all properties that are intended to be sent to Auth0 as part of the auth process into a authorizationParams or logoutParams object.

The code changes in this PR in summary:

• The existing BaseLoginOptions has now become AuthorizationParams, this holds the parameters that will be sent to the Authorization Server (Auth0) and is where custom parameters to send along also can be set
• A new BaseLoginOptions interface was added that simply contains authorizationParams?: AuthorizationParams and the existing interfaces continue to extend that, with the exception of GetTokenSilentlyOptions which only contains a subset of AuthorizationParams properties by nature
• LogoutUrlOptions and LogoutOptions now contain a logoutParams object that holds parameters to be sent to the logout endpoint, this object also supports the same custom parameters allowance like authorizationParams,

As a developer using the SDK, a summary is that any properties relevant to the Authorization Server (Auth0) or custom parameters that were provided now need to be moved into a authorizationParams object and for Logout Endpoint related parameters or again any custom parameters provided to the Logout Endpoint should now be provided in a logoutParams object. An example (but not exhaustive) diff of these changes follows.

• Auth0Client constructor

const auth0 = new Auth0Client({
  clientId: '<AUTH0_CLIENT_ID>',
  domain: '<AUTH0_DOMAIN>',
- scope: '<MY_SCOPE>',
- redirect_uri: '<MY_CALLBACK_URL>',
- custom_param: 'custom value'
+ authorizationParams: {
+   redirect_uri: '<MY_CALLBACK_URL>',
+   custom_param: 'custom value',
+   scope: '<MY_SCOPE>'
+ }
});

• createAuth0Client helper

const auth0 = await createAuth0Client({
  clientId: '<AUTH0_CLIENT_ID>',
  domain: '<AUTH0_DOMAIN>',
- scope: '<MY_SCOPE>',
- redirect_uri: '<MY_CALLBACK_URL>'
- custom_param: 'custom value'
+ authorizationParams: {
+   redirect_uri: '<MY_CALLBACK_URL>'
+   custom_param: 'custom value',
+   scope: '<MY_SCOPE>'
+ }
});

This change should also be made to the buildAuthorizeUrl, checkSession, getTokenSilently, getTokenWithPopup login, loginWithPopup, and loginWithRedirect APIs.

• auth0.buildLogoutUrl

auth0.buildLogoutUrl({
- returnTo: '<MY_RETURNTO_URL>'
- custom_param: 'custom value'
+ logoutParams: {
+   returnTo: '<MY_RETURNTO_URL>'
+   custom_param: 'custom value'
+ }
});

• auth0. logout

auth0. logout({
  localOnly: true,
- returnTo: '<MY_RETURNTO_URL>'
- custom_param: 'custom value'
+ logoutParams: {
+   returnTo: '<MY_RETURNTO_URL>'
+   custom_param: 'custom value'
+ }
});
