Support for OIDC activation type

[hvge]

The new PowerAuth stack 1.9+ will directly support new OIDC activation type. This ticket is about to add this functionality to the mobile SDK. As a part of this change, we should deprecate all activation-related methods except method using PowerAuthActivation object at its input.

Required Changes

Reuse of Existing Custom Activation Type

There will be no new activation type for OIDC, there will be just a CUSTOM activation with specific implementation for OIDC.

As part of this functionality we will introduce DIRECT activation type, which will be an alias for CUSTOM activation type.

Let's call the custom activation type direct in this specification.

Direct Activation Type Parameters

Following parameters are used during OIDC activation:

• method - oidc - to separate from other custom activations and enable default functionality in enrollment server
• providerId - OAuth 2.0 provider identification
• code - OAuth 2.0 authorization code
• nonce - nonce used in the OAuth 2.0 flow
