Issue:
framework和plugin配置里关于 path 信息处理的问题
现在framework和plugin 的配置里都有 path 或者 package 信息，
对于 package 的场合问题不大，因为有用到 require.resolve 。

而 path 的场合，是直接处理成相对/绝对路径，这里其实有点问题

比如我一个 framework 或 plugin 是不打算发布到 registry 的，那我肯定长期使用 path 的配置去引用，
那我建议需要参考这个包的 package .json 的 main 属性，而不是指定到具体的 dist 、 build 、libs 这样的目录位置。

Pull request:
refactor(loader): format plugin config in factory && support inline package
resolve #228 

主要改动：
- 移除 PluginConfigLoader，统一由 ConfigLoader 处理
- 移除扫描器最终对 `plugin-config` 的无意义过滤逻辑，manifest 中将继续包括 `plugin` 相关配置
- ConfigLoader 针对 `plugin` 使用新增的 PluginFactory.formatPluginConfig 进行 `package` 和 `path` 的解析/格式化
- `path` 字段支持内连 npm 包获取入口
- 单测调整

注：Framework 因为机制有待讨论，暂未修改 cc @JerrysShan
