transactions

Working on a project I ran into the documentation for customizing the Foreign Key.
The docs read:

// https://sequelize.org/master/manual/assocs.html
// For example, to use UUID as the foreign key data type instead of the default (INTEGER), you can simply do:

const { DataTypes } = require("Sequelize");

Foo.hasOne(Bar, {
  foreignKey: {
    // name: 'myFooId'
    type: D

这里的任务比较多，您仅需要上手做一到两个，熟悉流程之后，就可以去做更有挑战的任务，参考 #93

• dtmsvr/storage下的文件，可以加上开源版权注释，每个文件的一行作为一个任务，发一个PR
• dtmcli/dtmimp/trans_xa_base.go中的中文注释翻译成英文注释，每行注释翻译，作为一个任务，发一个PR
• dtmcli/tcc.go中的注释翻译，同上
• 运行make之后，修复其中一个golangci-lint检测出来的问题，发一个PR

Sometimes we need to store a reference to an error object somewhere in the code so that we can return it to users. A good example is net.box: if the state machine is in the error state, we should return the error that caused the failure to all user requests. The problem is a user that got an error may link it to another error with [error.set_prev](https://www.tarantool.io/en/doc/latest/reference

Our versioned containers implement into_v1, as_v1, as_mut_v1 separately. To make this look more rusty I propose:

• find all instances of into_v1 in the code and replace them with implementation of From trait
• find all instances of as_v1 in the code and replace them with implementation of AsRef trait
• find all instances of as_mut_v1 in the code and replace them with implement
