Performance analysis tooling

[novoj]

We want to extend evitaLab with a new view that would list all recent requests and queries / mutations executed within them and visualise them in a comprehensible way. This tooling will build on a new facility in evitaDB that allows to store executed queries in the file log and aggregate them with mutations in WAL and provide the tooling with an aggregated view over them.

We know from previous experience that such tools are crucial for the development of high performance applications. Developers make many errors (often N+1 errors) that are difficult to track without such tools. When the list of all queries to the database is visible and can be traced back to a particular page/request, developers can much better reason about the problems.
