Feat/main/dcr fallback with mtls

[anestos]

I m boostraping the mtls client authentication. I guess we need to match the types expected by the SDK somehow:

    /**
     * Mutual Transport Layer Security (MTLS) authentication method.
     *
     * @property clientKeyStore The client KeyStore.
     * @property clientKeyStorePassword The password for the clientKeyStore.
     * @property serverTrustStore The server TrustStore.
     */
        val clientKeyStore: @RawValue KeyStore,
        val clientKeyStorePassword: CharArray,
        val serverTrustStore: @RawValue KeyStore
     

@daniellindau any ideas how to do that?

Variable declaration is missing initialization. The variable clientAuthenticationMethod must be initialized or use an explicit type annotation. Consider using:

val clientAuthenticationMethod: ClientAuthenticationMethodConfiguration

or initialize it inline with an if expression:

val clientAuthenticationMethod = if (conf["client_authentication_mtls"] as? Boolean? ?: false) {
    // ...
} else {
    // ...
}

Suggested change

	val clientAuthenticationMethod
	val clientAuthenticationMethod: ClientAuthenticationMethodConfiguration

Duplicate parameter entry. The parameter registration_secret is already documented on line 28. This duplicate entry on line 33 should be removed.

Suggested change

`registration_secret` | android | false | | Name of the template client to be used in fallback. Required if fallback registration should be used.
