Benchmarkdotnet: Implement `--list`

[adamsitnik]

Implement --list which is going to print all of the available full benchmark names that can be used for filtering.

I would like to try to do it next week.

Can the display be a tree structure like, using namespace -> type -> method? In CoreFx there are more that thousand micro benchmarks, and a single/flat list would not be very helpful.
For example,
Instead of displaying:

System.Buffers.Binary.Tests.BinaryReadAndWriteTests.MeasureReverseEndianness
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.MeasureReverseUsingNtoH
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.ReadStructAndReverseBE
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.ReadStructAndReverseLE
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.ReadStructFieldByFieldBE
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.ReadStructFieldByFieldLE
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.ReadStructFieldByFieldUsingBitConverterBE
System.Buffers.Binary.Tests.BinaryReadAndWriteTests.ReadStructFieldByFieldUsingBitConverterLE

You could display (option 1):

System.Buffers.Binary.Tests.BinaryReadAndWriteTests
  MeasureReverseEndianness
  MeasureReverseUsingNtoH
  ReadStructAndReverseBE
  ReadStructAndReverseLE
  ReadStructFieldByFieldBE
  ReadStructFieldByFieldLE
  ReadStructFieldByFieldUsingBitConverterBE
  ReadStructFieldByFieldUsingBitConverterLE

Or display names split to the namespace level as nodes can have more tests (option 2):

  Buffers
    Binary
      Tests
        BinaryReadAndWriteTests
          MeasureReverseEndianness
          MeasureReverseUsingNtoH
          ReadStructAndReverseBE
          ReadStructAndReverseLE
          ReadStructFieldByFieldBE
          ReadStructFieldByFieldLE
          ReadStructFieldByFieldUsingBitConverterBE
          ReadStructFieldByFieldUsingBitConverterLE

I like @jorive idea!

You could have an option like this: --list-benchmarks:[flat|tree]

[WojciechNagorski]

It shouldn't be problem. I've seen similar feature here:
