Refactoring roles and permissions names

[hiqsol]

Roles:

• role:client, role:support, role:manager
• role:bill.manager, role:domain.freezer

Permissions:

• domain.set-contacts
• bill.update, bill.create, bill.delete

Another variant use uppercase for roles (less attractive):

• CLIENT
• ADMIN
• BILL.MANAGER

public function testMighty()
{
    $this->auth->setSmartAssignments(['admin', 'manager', 'bill.create', 'domain.freeze'], 'user:mighty');
