Evaluate a user's hardware and setup using BenchBuddy

[jgresham]

Feature details

Users want to know if their setup is good enough to run a node. We currently check disk size, cpu counts, etc, but we do not do any speed tests. SSD Input Ouput per second (IOPS), cpu speed, and internet speed are all easily checked with (fromerly Speedometer) BenchBuddy!

• For now, this will be initiated through the system monitor screen or through a menu item. (inform the user that all nodes should be stopped before running the test, but don't stop the user)
• It will then send an ipc command to the main process to run BenchBuddy (currently named speedometer https://github.com/NiceNode/speedometer)
• The -f json flag will be used with BenchBuddy so that NiceNode can easily parse the output!
• The results of speedometer will be shown to the user in System Monitor or in a modal/notification
