Remove the `block_reseller_customer` feature flag
Problem
Once the block_reseller_customer
feature flag has been on for a while and the features are stable, the legacy will need to be removed.
Proposal
Once we've vetted the feature, we should remove block_reseller_customer
feature flag checks from the code and remove the legacy code. Also, remove the temporary rake task, reseller_customers:deactivate_login
, introduced in !1464.
After the MR merges and deployed into production, we can safely remove the feature flag from https://gitlab.com/gitlab-org/customers-gitlab-com/-/feature_flags.
Result
A cleaner code base.
