feat: tiny bench

[tanmoysrt]

Goals

• Only Mumbai, India region (configuration)
• Need to ensure that tiny bench's site doesn't get scheduled only on the benches where larger plan's site is deployed
• HTTP request timeout for 30 seconds (Manually)
• Scheduler tick interval 10 minutes (Manually)
• No skip auto update
• Restrict the apps to only frappe apps
• Need to ensure that other plan’s app doesn’t get scheduled to these bench’s server
• In change plan, people can’t downgrade to 5 dollar one
• Redesign the site creation page or maybe create a new page

Note

Currently, if user selects a non-allowed app or different region, the plan becomes non-selectable instead of completely removed from UI. It will be better to show the reason to user, why the plan is non-selectable/disabled.

• Add testcases
  • Validation of downgrading to restricted site plan
  • Validation of restriction of disabling auto update for sites in public bench
  • Validation of specific allowed apps for site plan
  • Validation to check if larger plan's site doesn't get deployed to this plan's specific benches/servers
  • Validation to check if these specific plan (tiny plan)'s bench get deployed to only to the selected release group / bench specified in Site Plan

Tip

CPU time constraints for background job (For Later Version)

• Track the CPU usage
• Custom dequeue strategy to stop picking someone’s task if they hit quota
