swarm: network simulation for swarm tests (#769)
* cmd/swarm: minor cli flag text adjustments * cmd/swarm, swarm/storage, swarm: fix mingw on windows test issues * cmd/swarm: support for smoke tests on the production swarm cluster * cmd/swarm/swarm-smoke: simplify cluster logic as per suggestion * changed colour of landing page * landing page reacts to enter keypress * swarm/api/http: sticky footer for swarm landing page using flex * swarm/api/http: sticky footer for error pages and fix for multiple choices * swarm: propagate ctx to internal apis (#754) * swarm/simnet: add basic node/service functions * swarm/netsim: add buckets for global state and kademlia health check * swarm/netsim: Use sync.Map as bucket and provide cleanup function for... * swarm, swarm/netsim: adjust SwarmNetworkTest * swarm/netsim: fix tests * swarm: added visualization option to sim net redesign * swarm/netsim: support multiple services per node * swarm/netsim: remove redundant return statement * swarm/netsim: add comments * swarm: shutdown HTTP in Simulation.Close * swarm: sim HTTP server timeout * swarm/netsim: add more simulation methods and peer events examples * swarm/netsim: add WaitKademlia example * swarm/netsim: fix comments * swarm/netsim: terminate peer events goroutines on simulation done * swarm, swarm/netsim: naming updates * swarm/netsim: return not healthy kademlias on WaitTillHealthy * swarm: fix WaitTillHealthy call in testSwarmNetwork * swarm/netsim: allow bucket to have any type for a key * swarm: Added snapshots to new netsim * swarm/netsim: add more tests for bucket * swarm/netsim: move http related things into separate files * swarm/netsim: add AddNodeWithService option * swarm/netsim: add more tests and Start* methods * swarm/netsim: add peer events and kademlia tests * swarm/netsim: fix some tests flakiness * swarm/netsim: improve random nodes selection, fix TestStartStop* tests * swarm/netsim: remove time measurement from TestClose to avoid flakiness * swarm/netsim: builder pattern for netsim HTTP server (#773) * swarm/netsim: add connect related tests * swarm/netsim: add comment for TestPeerEvents * swarm: rename netsim package to network/simulation
