Nodes on the chain with GPUs has be querable

[muhamadazmy]

Users of the grid need to be able to find and query available nodes that has GPUs

• allow a node to set gpu to true/false
• add client methods
• add graphql indexing

How we implemented #726 is pretty generic in a way that the concept allows to set an extra price for additional "features" that a node has. So querying this storage map gives a list of nodes that have an extra price attached which can then be queried via RMB for a list of features (gpu, high end cpu, ...)

We came to the solution that we will store a boolean in a seperate storage map that indicates if the node has a GPU or not, this can be set by the node itself and also be queries by the clients.

can be deployed when threefoldtech/tfchain_graphql#105 is merged and released

Verified on devnet.

tfchain

from polkadot UI -> Chain State -> tfgridmodule nodes with gpus can be queried using nodeGpuStatus

and extra fees can be queried from Chain State -> smartContractModule -> dedicatedNodesExtraFee

graphql

Nodes with gpu can be queried from graphql as seen in threefoldtech/tfchain_graphql#104 (comment)
