minidoc: training document changes and updates

[aherna]

***Module 1

• Slide 16 – Don’t need OSPF for router sandwich because the router serves as the default gateway to both networks and it knows how to get everywhere.
• Should use router router dhcp 10.0.0.0 router 10.0.0.1 and router router dhcp 20.0.0.0 router 20.0.0.1 instead of ospf. This sets default gateway as part of dhcp process for vms

***Module 2.5

• Should probably rename this as its own module like module 3 and increment the others
• Slide 5 should talk two how the containers are implemented in minimega as they are different than using docker or LXC linux containers

***Module 3

• Slide 22 link to module 4 title doesn’t match module miniweb vs visualization

***Module 4

• Slide 5 consider changing first bullet to say if you like the minimega console to be available in the web application…

***Module 5

• LGTM

***Module 6

• Slide 7 We may want to mention its probably better to use minirouter or some other vm to control dhcp and not use the host?
• Slide 8. We support BGP now in current 2.6 build among other features
• Slide 15, BGP is already implemented
• Potentially link the following articles - /articles/ospf_cost.article, Look at the router API additional commands (about 9 routing commands)

***Module 7

• Do we want to add versioning pitfalls or troubleshooting?
