Add ChecksSelection component

[dottorblaster]

Just externalized the checks selection into a component of its own. Stories available 🤘

@nelsonkopliku @EMaksy I will be away for a couple weeks, so I'll leave some notes on this to make the merge and the iteration (if any) easiest as it can be.

• The logic that displays the selected checks has been simplified a bit
• You can use the onClear handler to clear any redux state that holds any saga result. It gets called every time a check gets selected, and on mount
• The component is completely drop-in: remaining stuff is using this to build the actual hosts check result page and dropping this into the old clusters checks selection page, making the same component declared locally into that directory (ClusterDetails) useless (and the directory itself slimmer).

Right now I don't have any other remark in my mind but feel free to ask!

Fantastic job man!
Eager to see how it will be applied in the cluster and host views 🙂

@arbulu89 addressed the feedbacks and took the opportunity to align naming from resource to target in 27e715a

Thank you @nelsonkopliku

PD: Still added a comment XD, but no need of a new review, the code looks great
