dev: TypeORM for ydb-nodejs-sdk

[asmyasnikov]

Make YDB support in TypeORM (https://typeorm.io).

Since the topic is large, the work is divided into stages

Legend:

    □ - need to be written and tested

    ± - in the code, but not tested yet

    🗸 - done and tested

1. □ Add support for Generic Query Service, which will be used to retrieve data for TypeORM (dev: Add generic query service #337).

2. □ Implement a minimal set of methods to support functionality listed in the TypeORM Quick start (https://typeorm.io/#quick-start)
   Keep already existing code from https://github.com/ydb-platform/typeorm and test it.
   Interface methods required for the Quick start are collected by trace - for details see https://github.com/Zork33/typeorm/tree/planning-steps-for-implementation

• □ YdbDriver:afterConnect #351
• ± YdbDriver:buildTableName
• ± YdbDriver:connect
• ± YdbDriver:disconnect
• ± YdbDriver:createGeneratedMap
• □ YdbDriver:createParameter
• ± YdbDriver:createQueryRunner
• ± YdbDriver:createSchemaBuilder
• ± YdbDriver:escape
• ± YdbDriver:escapeQueryWithParameters
• □ YdbDriver:findChangedColumns
• □ YdbDriver:getColumnLength
• □ YdbDriver:isReturningSqlSupported
• □ YdbDriver:normalizeDefault
• □ YdbDriver:normalizeIsUnique
• ± YdbDriver:normalizeType
• □ YdbDriver:obtainMasterConnection
• ± YdbDriver:parseTableName
• □ YdbDriver:prepareHydratedValue
• □ YdbDriver:preparePersistentValue
• ± YdbQueryRunner:commitTransaction
• ± YdbQueryRunner:connect
• □ YdbQueryRunner:getCurrentDatabase
• □ YdbQueryRunner:getCurrentSchema
• □ YdbQueryRunner:hasTable
• ± YdbQueryRunner:rollbackTransaction
• ± YdbQueryRunner:query
• □ YdbQueryRunner:release
• ± YdbQueryRunner:startTransaction

3. □ Realize the generation of migrations scripts based on the existing Postgres example

4. □ Make an example of seeding (initial filling of dictionaries) on the basis of migrations scripts.

5. □ It is desirable that the model of types was as close as possible to postgres implementation, to facilitate the transition

6... Further implement the rest of YdbDriver and YdbQueryRunner methods. There are less than half of them in the initial list

Depends from:

• dev: Add generic query service #337
