feat: add script to hibernate spaces

[wa0x6e]

Pitch: https://github.com/snapshot-labs/pitches/issues/65

• Update schema for new hibernated column
• Add a script to hibernate spaces (or see feat: add script to hibernate spaces #197 (comment) for the direct SQL query)
• Auto reactivate space on settings update (will require feat: add hibernate and reactivate actions to moderation #240)

Usage

• yarn ts-node scripts/hibernate.ts run will hibernate inactive spaces
• yarn ts-node scripts/hibernate.ts preview will show the number of spaces, eligible for hibernation

Note

This is PR is only about supporting the new hibernated column, as well as putting spaces to hibernation, and does not handled any kind validation (which requires coordination with UI, and come in a later PR)

[wa0x6e]

Script has been stripped down to hibernate only spaces inactive more than 1 year ago, and SQL queyr is now simple enough to not warrant a script.ts anymore.

Running the following SQL query will hibernate the spaces.

WITH toHibernate AS (
      WITH data AS (
        SELECT
        id,
        (SELECT MAX(end) FROM proposals WHERE space = spaces.id LIMIT 1) AS lastProposalEndDate
        FROM spaces
        WHERE hibernated = 0
      )

      SELECT
        id, lastProposalEndDate
        FROM data
        WHERE
        # Filtering out spaces that have not been active in the past year
        FROM_UNIXTIME(lastProposalEndDate) < DATE_SUB(CURRENT_DATE, INTERVAL 1 YEAR)
    )
    UPDATE spaces SET hibernated = 1 where id IN (id)

Feel free to merge this one, or just run the query separately, and close this PR
