irregular distribution of grid endpoints over all nets

https://github.com/threefoldtech/zos/blob/main/pkg/environment/environment.go#L107-L167

Describe the solution you'd like

Ops maintains two full backend stacks for each net, so each net has a spare url for each service to stay operational. zos currently makes use of this but does not make use of all available endpoints. Following list lacks in the config:

Devnet

TFchain

• wss://tfchain.02.dev.grid.tf

Activation service

• https://activation.02.dev.grid.tf/activation/activate

Graphql

• https://graphql.02.dev.grid.tf/graphql

---

QAnet

Relay

• wss://relay.02.qa.grid.tf

Activation service

• https://activation.02.qa.grid.tf/activation/activate

Graphql

• https://graphql.02.qa.grid.tf/graphql

---

Testnet

TFchain

• wss://tfchain.02.test.grid.tf

Activation service

• https://activation.02.test.grid.tf/activation/activate

Graphql

• https://graphql.02.test.grid.tf/graphql

Mainnet

TFchain

• wss://tfchain.02.grid.tf
