Deploy anonymous credentials to prod [Checklist]

[LDiazN]

This checklist provides all the checks and actions to take for migrating anonymous credentials to prod:

• Make sure the s3 credentials bucket is deployed and accessible
• Make sure ssm parameter for secret key is deployed
• Run the following query for adding new columns to the fastpath (see Anonymous credentials draft endpoints backend#1016)

ALTER TABLE fastpath ON CLUSTER oonidata_cluster 
ADD COLUMN is_verified Int8 default 0,
ADD COLUMN nym String default '',
ADD COLUMN zkp_request String default '',
ADD COLUMN age_range String default '',
ADD COLUMN msm_range String default '';

• Update fastpath version running in prod with the following command

./play -i inventory -l fastpath.prod.ooni.io deploy-fastpath.yml  --diff

• Update ooniprobe version running terraform, see: Anonymous credentials deployment to prod #311
• Make sure measurement upload workflow is not disrupted, keep an eye on ooniprobe logs, check fastpath logs, make sure files are being written to disk
• Merge Anonymous credentials draft endpoints backend#1016
