[cloud][CLOUD-356] Change default invite quota for users
Created by: kopancek
Description
Right now the default invite quota is 15. However we expect cloud open beta customers to be able to invite ~100 developers in their organization.
Changing the default quota to 100 to adhere to this expected size. Otherwise we would need more than 1 person to invite the organization members (or change the quota in the DB directly on-demand), which is not desired.
Test plan
Tested the migration against local postgres instance and it worked flawlessly.
