Feature/unpack predictions

[Galileo-Galilei]

Description

closes #93 #99

Development notes

Compare to what is discussed in #93, I:

• make inference pipeline a property to validate it has only one output when set
• added an output_name attribute in KedroPipelineModel
• unpacked the result of the predict method of KedroPipelineModel

But I skipped output validation which is much trickier and belong to another PR.

PS: I fixed a few docs typo n the way in a separated commit.

The coverage decrease is due to a test. I've added a commit to ignore the tests folder in coverage for further PR.

[takikadiri]

I just left some remarks in the docs and the predictions's unpacking method, otherwise it's good for me !

@takikadiri I let you merge when all checks are ok!
