重构服务插件架构，移除冗余功能

Browse Source 
- 统一所有服务插件的实现模式，移除i18n国际化依赖
- 删除硬编码的备份凭据列表，统一使用GenerateCredentials()
- 移除过度工程化的Context取消检查
- 清理exploitation功能，专注于弱密码检测和服务识别
- 简化代码结构，移除冗余注释和说明文档
- 优化19个服务插件：activemq, cassandra, elasticsearch, ftp, kafka, ldap, memcached, mongodb, mssql, mysql, neo4j, oracle, postgresql, rabbitmq, rsync, smtp, snmp, telnet, vnc
- 代码总量减少约40%，提升维护效率

此次重构确保插件架构的一致性和简洁性
