New SnowflakeQueryFromFile Task and SQLServerExecute Fix

[kvnkho]

Summary

This creates a new task for SnowflakeQueryFromFile. Some users have been looping through .sql files with the ShellTask so this should help them.

The second fix is fixing the MS SQL Server execute Task. This was broken because the library can not take in kwargs. This fix is too hard to test I think.

Checklist

Edit - I edited the SnowflakeQueryFromFile to SnowflakeQueriesFromFile. It now takes in multiple SQL queries and returns a list of results of the queries.

This PR:

• adds new tests (if appropriate)
• adds a change file in the changes/ directory (if appropriate)
• updates docstrings for any new functions or function arguments, including docs/outline.toml for API reference docs (if appropriate)

[kvnkho]

This is done.

What is the SQLServerExecute fix?

What is the SQLServerExecute fix?

cursor.execute(query=query, vars=data) breaks because execute cannot take kwargs.

I believe this is done now.

I updated this. Couple of changes.

1. I wrote a test for the SqlServerExecute fix. This test makes sure that kwargs are not passed to the .execute() method because that throws errors (seen in the linked issue)
2. I updated SnowflakeQueriesFromFile to match the latest updates to SnowflakeQuery from master. Mainly, it takes in a cursor_type that can change the return.
3. I removed MySQL changes from this PR from last time because there were too many merge conflicts with the latest master. It doesn't belong here anyway.

I'm a bit confused about the docs failure, can you push a commit to retrigger? git commit --allow-empty -m "Force docs rebuild"

This can be entirely omitted

[kvnkho]

Just making sure, you mean to omit the entire except block right? My concern was that the error won't be raised, but I guess it's passing the test for the error to pass through.
