[WIP] dagster-mssql

[nico525]

Summary

This work in progress PR adds basic mssql backend functionality for run, event and log storage. It relies on pyodbc and mssql odbc driver provided by microsoft. The decision is based on pymssql's future being unclear with only few maintainers. See here for details.
Most of this is copied over from postgres and mysql libraries, but adjusted to some minor database specifics of mssql.

Test Plan

There is no Test Plan, yet! I am happy to receive any further support on this by other maintainers.

Checklist

Hi nico525, How to get the changed files and deply on my local setup. i want to try them. Thanks

@nico525 thanks for the contribution and sorry that it took us a long time to get to it. I think this is the kind of contribution that we would prefer to live outside of the core Dagster repo at this time, as the core team of Dagster maintainers doesn't have the mssql expertise that would be required to maintain this going forward. If you wanted to post a repository with this integration, we would love to link it from our docs.

I'm going to close this PR for bookkeeping purposes. Feel free to reopen if you'd like to argue that this should go into the main dagster repo.

[nico525]

Sorry for the radio silence. Somehow missed the comments on this.
Unfortunately, I will not be able to host a package on my own without any further support and will be closing the fork due to this pretty soon. If anyone is up to maintaining this, please feel free to contact me.

I am now using dagster_mssql in an UAT environment and will probably maintain it on an ongoing basis (although not that regularly as you release versions...) if we decide to use it in an production environment
The package is far from perfect, but I just performed the 1.0.1 upgrade 👍
