Add ability to expand/collapse a multijob view at the phase and name levels

[RochaStratovan]

As a user I would like the ability to be able to expand and collapse the multijob phases, as well as the multijob itself (for nested multijobs).

For example, if I have the 'leaf level' multijob to work on the foobar project it might have the following display output.

• Foobar Master Trigger (multijob name)
  • Build (phase name)
    • Build foobar on linux
    • Build foobar on mac
    • Build foobar on windows
  • Test (phase name)
    • Test foobar on linux
    • Test foobar on mac
    • Test foobar on windows
  • Distribute (phase name)
    • Create linux installer
    • Create mac installer
    • Create windows installer

I would like to have a toggle or button or ability to collapse this so that it would only show multijob name and it's phases. For example:

• Foobar Master Trigger (multijob name)
  • Build (phase name)
  • Test (phase name)
  • Distribute (phase name)

And the ability to again, collapse this to see just the multi-job name

• Foobar Master Trigger (multijob name)

This would be beneficial to me because we have nested multijobs for our different products. Some times I want to see the details, sometimes I want to see the summary (well, the managers want to see the summary.....)

For example, if we have just three projects where we build a common library and then two products that use the common library, it could look something like the following in detailed view:

• Master Build Trigger (multijob name - level 1)
  • Common Library Master Trigger (multijob name - level 2)
    • Build (phase name)
      • Build common library on linux
      • Build common library on mac
      • Build common library on windows
    • Test (phase name)
      • Test common library on linux
      • Test common library on mac
      • Test common library on windows
    • Distribute (phase name)
      • Create linux installer
      • Create mac installer
      • Create windows installer
  • Foobar Master Trigger (multijob name - level 2)
    • Build (phase name)
      • Build foobar on linux
      • Build foobar on mac
      • Build foobar on windows
    • Test (phase name)
      • Test foobar on linux
      • Test foobar on mac
      • Test foobar on windows
    • Distribute (phase name)
      • Create linux installer
      • Create mac installer
      • Create windows installer
  • Blarg Master Trigger (multijob name - level 2)
    • Build (phase name)
      • Build blarg on linux
      • Build blarg on mac
      • Build blarg on windows
    • Test (phase name)
      • Test blarg on linux
      • Test blarg on mac
      • Test blarg on windows
    • Distribute (phase name)
      • Create linux installer
      • Create mac installer
      • Create windows installer

If I could collapse the multijobs at the multijob name level as well as at the phase level then I can see the hierarchical display without being overwhelmed with the details. I can drill down into the details as desired.

For example, if collapse at the names, the above could be summarized as:

• Master Build Trigger (multijob name - level 1)
  • Common Library Master Trigger (multijob name - level 2)
  • Foobar Master Trigger (multijob name - level 2)
  • Blarg Master Trigger (multijob name - level 2)

It would also be nice if there were options such as

1. collapse/expand all
2. collapse/expand all below this point

To make managing the viewing of nested multijobs easier.
