[Devmon] Inheriting some configuration from Hobbit

[Buchan M. <bg...@st...>]

There are at least two tracker items that relate to reading some Hobbit 
configuration (to avoid the need to configuring devmon for things already 
configured on Hobbit).

The existing solutions parse hobbitserver.cfg or similar (which then also 
requires configuration of where to find hobbitserver.cfg).

Instead, I think it may be better for some of the devmon configuration items 
to default to Hobbit environment variables if present. The idea then would be 
to run devmon under bbcmd (IOW, only the devmon init script needs to know 
where bbcmd is).

In the BB case, the init script would just need to source bbdef.sh I think.

In the case where devmon is installed stand-alone, there should be no 
difference.

However, I would like to know what devmon users think of this option. Is there 
any scenario I have missed, or some reason this would be worse than attempting 
to parse hobbitserver.cfg (or hobbitclient.cfg, or bbdef.sh, or anything else 
that may differ from the actual Hobbit/BB environment)?
