Enhance the infra recommendation algorithm for VM OS image

[yunkon-kim]

• Modularize text similarity features into strcomp pkg
• Predefine the known architecture information as a map because text similarity comparison is not possible.
• Improve the recommendation accuracy/performance through the combined use of map search and SequenceMatcher

I'd like to show the 2 example cases by following logs.

Case 1

• Similarity Score: 0.69
• Items found to be similar: 5 items
