[Requestor enchancement] Advertise network speeds and geolocation in the offer templates on the network

[cryptobench]

With the introduction of outbound networking + SocketProxy and in the future inbound networking, I think it's worth considering adding network speeds and geolocation to the offers advertised by providers on the network.

Why?

1 ) If I am to spawn services on a provider that might be pulling a lot of bandwidth, then as a requestor I would like to select the provider machines that I know has the speeds required to meet my demand. We have users in our discord that are providers and have mentioned they have 10 mbit speeds, and in a lot of case this might bottleneck a lot of things because there is a high chance that not only is the user and possibly other family members are using the providers connection at the same time as you would (the requestor).

2. Right now if I want to spawn services on a provider its a lottery for me in regards to knowing how fast their network speeds are. This can heavily bottleneck my service if its slow and it will be painful to debug for the requestors because either we have to launch some benchmarking service on the provider to confirm (which also == $$$$$) or the requestor might sit and think "wtf is wrong with my service? It works fine locally but once it starts on golem it doesn't respond or is super slow... this platform sucks I will find something else" OR third, the requestor will try more providers and on some it works perfectly fine and others it doesn't.... which is even more confusing

We already know that debugging tasks/services running on top of Golem is hard, but not knowing the network speeds of the provider can introduce even more pain points for requestors using our platform.

It's a vital piece of information now that we're stepping into the dApp territory. Golem was mainly batch processing backthen which meant that only cores, disk and memory were relevant for requestors, but times are changing and now network information needs to be available to provide a satisfiable experience when working with services on Golem.
