perf config: Add support for getting config key-value pairs
Add a functionality getting specific config key-value pairs.
For the syntax examples,
perf config [<file-option>] [section.name ...]
e.g. To query config items 'report.queue-size' and 'report.children', do
# perf config report.queue-size report.children
