Add info about active scmOverrides about bob

[rhubert]

I think extending 'bob query-scm' is basically a good idea, but maybe it's not used without a hint that scmOverrides are active. What about a build-summary?

Build result is in dev/dist/root/1/workspace
- Build time: 1d 2h 3m 4s
- packages build: 42 downloaded: 123
- active scmOverrides for packages: a,b,c,d

After #100 is implemented the shared packages could also be shown.

I really like the idea of the summary. 👍 I was also thinking about an "info" command that tells you either some general information about the project or detailed information about a package (how much variants, active overrides, you name it...).

[rhubert]

The info command sounds interesting. Maybe in the future recipes have a optional 'info:' section where you can add some human readable info's about the package,... But I think you may need a lot of arguments for the info command. Otherwise you'll possibly get to much informations on large projects?

Maybe the scmOverrides-info can also be added to the status command?

[rhubert]

I started working on this (see #109) and added some statistics as well as informations on overridden scm.

Example Output:

bob dev ...
Build result is in ....
checkoutSteps: 2
buildSteps:    2
packageSteps:  2
scms: 2
 -> overridden: 1
   -> packages: ['root']

bob status root
>> root
scm's Overridden by override:
match: {'url': 'file:///tmp/test/'}
matched to:
{'url': 'file:///tmp/test/', 'dir': 'test', 'scm': 'git', 'recipe': 'recipes/root.yaml#0'}

Now I'm thinking about adding a 'name' property to scmOverride to increase readability of status output.... 🤔
