[SNOW-177]Convert teammember_latest to dynamic table

[danlu1]

Problem:

Currently, the teammember_latest table is a table that is updated via upserting task that are based on teammembersnapshots stream. We want to convert it to dynamic table so it gets refreshed automatically.

Solution:
Following the instructions of this SOP:

• Add a script to create a backup of the original teammember_latest table which need to be removed manually after validation
• Add a script to delete the upserting task for the original teammember_latest table
• Add a script to delete stream for teammembersnapshots table that is referred in teammember_latest upserting task
• Add a script to drop the original teammember_latest table so we can create a dynamic table with the same name
• Create teammember_latest dynamic table and add table and column comments at the same time according to the newest SOP.

Wait for others review before merging, but this looks good to me.

It also just occurred to me that we should probably be doing these dynamic table conversions in two PRs:

1. Creation of the dynamic table
2. (Validation)
3. Deletion of old table and related objects

This allows us to compare the upsert behavior of the dynamic table to that of the original table. That's something we don't get with a static backup of the original table.
