Data migration tool to import data into Marten

[mysticmind]

Provide a generic data migration tool to ease the process/reduce friction to import data into Marten from other data sources such as SQL Server, CSV etc.

CosmosDB team has built a tool which provides both GUI and commandline tools to import data from JSON files, MongoDB, SQL Server, CSV files, Azure Table Storage, Amazon DynamoDB, HBase, Azure Cosmos DB collections. Source code is available in GitHub and MIT licensed. You can refer to documentation here. This helps to pick some ideas to build a data migration tool covering several data sources.

Closing this, we can revisit this enhancement later.

@mysticmind I think that maybe we could keep it open to not forget about that? I see this really useful, especially for migration from the relational databases (so help potentially migration from EF).

Okay, re-opening this issue
