[ghost]

Ref：
1）eggjs/egg-cookies#12
2）eggjs/egg-cookies#11
3）#2949
4）eggjs/egg-cookies#15

In short：
The Egg's cookie isn't inheriting from Koa's Context's cookie, we should rewrite it by adding 'encrypted' as the prop.

@whxaxes：Notice that I've referred the latest version of egg-cookies's index.d.ts. And this has exposed 'ctx', which isn't a must in 'egg' because we don't use something like 'this.ctx.cookies.ctx.……'. So I've created another interface as a wrapper to disclose the 'ctx' and expose ONLY get/set methods. Correct me if any suggestions :)

Context 接口使用 RemoveSpecProp 这个方式扩展后 (index.d.ts L685)，tsserver 对 ctx 的补全就不包含 koa.Context 里面的字段了，改回之前的写法就没问题。请问可能是什么原因？

@jsl9208 之前是没问题的，现在我刚试了一下好像真的有这种情况，我查一下原因，之后发个 PR 修复

@jsl9208

找到原因了。。。最近 koa 的声明发了个版本，给 Context 加了 [key: string]: any 的声明，导致 keyof Context 就没法列出 koa.Context 里的所有属性了 ...

我今天想办法修复一下
