Upgraded azure identity to 1.12.1 to remove vulnerable dependency of simple-xml

• Simple-xml is a vulnerable package, and it comes from azure-identity.
• Upgrading azure-identity to 1.12.1 removes this dependency altogether.
• However, some netty classes were missing from azure-core so had to add the azure-core-http-netty instead of azure core. It solves below exception in the azure module:

Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.azure.core.http.netty.NettyAsyncHttpClientBuilder    Error: AppException(error=AppError(code=500, reason=Server error., message=An unknown error has occurred., errors=null, debuggingInfo=null, originalException=org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.azure.core.http.netty.NettyAsyncHttpClientBuilder), originalException=org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.azure.core.http.netty.NettyAsyncHttpClientBuilder)
