Adding default DNS server

[kylycht]

There was a problem installing dependencies on a device with our script service
The issue comes with connecting to the repo

Proposed solution is to add a 8.8.8.8 as default DNS server during device init

I am opening this as a discussion since some might think it is a user's responsibility to configure it

Here is issue that was encountered:

someone thinks that DNS issue should be resolved on DNS server itself, not on the board.

Device might be running on the network with bad connectivity to Goggle DNS or user running devices in private network and we putting user to the situation where he got no other choice than allowing Goggle DNS, which is not good

Moving this issue to issax main

[kylycht]

And your proposed solution is to leave it up to user to resolve DNS issue?

If you disagree, please add your alternative solution

[makeupsomething]

Issue moved to xshellinc/isaax-main #119 via ZenHub

@dbsparkle @kylycht
seems that configs are written only if you configure a board, if you skip this step would you like to configure your board (y/n): n then the secondary dns is not configured

is that ok?

[dbsparkle]

yeah, but lets add option in would you like to configure your board (y/n):y

Something like "Would you like to set a secondary DNS? (y/n):"

And if answer is yes then Enter an IP address for a secondary DNS

@dbsparkle I have added 8.8.8.8 as a secondary dns silently, so no need to enter ip address as explained in the description, or should I ask would you like to setup 8.8.8.8 as a secondary dns?

[dbsparkle]

Yeah, user must be aware of that kind of stuff.
