device-opc-ua: Migration of OpcUA connection properties from static configuration file to Protocol properties

[Ldsystem]

In my exploration of the EdgeX Foundry IoT platform and it's ecosystems, I've encountered a notable design choice regarding device-opc-ua library connection properties such as Security Policy, Security Mode, and Server Cert Path being placed within the configuration.xml file. Initially, I found this decision somewhat perplexing. My rationale was that these properties might vary between different OPC servers, leading me to consider whether configuring these properties through protocol-specific settings could offer greater flexibility.
