NIFI-15948 Switch HashiCorp Vault Client Service to SSLContextProvider

[exceptionfactory]

Summary

NIFI-15948 Refactors the StandardHashiCorpVaultClientService and supporting components to the use SSLContextProvider Controller Service interface instead of the SSLContextService for TLS communication.

This refactor follows the pattern of similar adjustments to SSL Context Service properties across extension components and uses the more generic SSLContextProvider.createContext() method instead of passing individual keystore and truststore properties.

For the HashiCorp Vault Client Service, changes include passing a property named javax.net.ssl.SSLContext, containing the created instance of the SSLContext object from the provider. Within the receiving StandardHashiCorpVaultCommunicationService, the constructor checks for the presence of the SSLContext property and builds the required JDK HttpClient and request factory. In absence of the SSLContext property, the constructor retains current behavior, supporting existing configurations that provide Vault SSL properties through external file configuration.
