so_vector - Add ES|QL queries profiling

[carlosdelest]

Adds ES|QL profiling metrics to the following ES|QL queries:

• esql-profile-knn-search-default-match-all
• esql-profile-knn-search-100-300-match-all
• esql-profile-script-score-query-match-all

The goal is to have a minimum set of different queries that gathers profile information so it can be analyzed in terms of time spent on the different phases.

The following metrics are retrieved from ES|QL profile and included into rally metrics:

• meta.query.took_ms: Total query time took
• meta.planning.took_ms: Planning time before query execution, includes parsing, preanalysis, analysis
• meta.parsing.took_ms: Time it took to parse the ESQL query
• meta.preanalysis.took_ms: Preanalysis, including field_caps, enrich policies, lookup indices
• meta.analysis.took_ms: Analysis time before optimizations
• meta..cpu_ms: Total plan CPU time
• meta..took_ms: Total plan took time
• meta..logical_optimization.took_ms: Plan logical optimization took time
• meta..physical_optimization.took_ms: Plan physical optimization took time
• meta..reduction.took_ms: : Node reduction plan generation took time
• meta...process_ms: Processing time for each operator in the plan
