backport #10744: engine/schema: create default network offering for vpc tier with conserve_mode=1 for fresh installation

[DaanHoogland]

Description

This PR… backports #10744.

Only new installations of 4.19.x will not have conservemode enabled by default vor VPCs. Upgrades from earlier versions will be alright. In order to make sure conserve mode is enabled for VPC-tiers, either create a clone of the default guestnetwork offering with conservemode enabled or execute the following sql:

-- Re-apply VPC: update default network offering for vpc tier to conserve_mode=1 (#8309)
UPDATE `cloud`.`network_offerings` SET conserve_mode=1 WHERE name='DefaultIsolatedNetworkOfferingForVpcNetworks’;
