Changes to Certificate Validation (#714)

* Changes to Certificate Validation - X509Chain is moved to be initated when certificate is being validated from the constructor of the class - X509ChainMock removed as X509Chain no longer can be mocked - Removed tests of X509Chain status as it no longer can be tested without a mock * Added link to migrate to rest in readme * Updated documentations and fixed tests

-## Migrere fra 5.0 til 5.2
+## Migrere fra SOAP til REST i 5.2 og senere versjoner
 
 Hovedendringer for 5.2 er nytt endepunkt for CPPA tjenesten. Det gamle endepunktet vil fortsatt fungere, men
 støtten for SOAP-endepunktet vil fjernes i en fremtidig versjon. Derfor anbefaler vi at alle oppgraderer

 ## Registre
 For å kunne kommunisere riktig med en mottpart, så er vi avhengig av å vite en del om protokoller, sertifikater, og kønavn. All denne informasjonen ligger i adresseregisteret og CPA-registeret.
