[FEATURE]: show path to report file via 'buildtest report path'

[shahzebsiddiqui]

Please describe your feature request

we should add a new subcommand buildtest report path that will print the full path to report file that is being used.

We can see list of report files via

(buildtest)  ~/Documents/github/buildtest/ [buildtest_buildspec_find_count] buildtest rt list
/Users/siddiq90/Documents/github/buildtest/var/report.json

Note that one can clear the report file hence there wont be any report so running any buildtest rt command or subcommand should just raise an exception

(buildtest)  ~/Documents/github/buildtest/ [buildtest_buildspec_find_count] buildtest rt clear
Removing report file: /Users/siddiq90/Documents/github/buildtest/var/report.json
(buildtest)  ~/Documents/github/buildtest/ [buildtest_buildspec_find_count] buildtest rt      
Unable to find report please check if /Users/siddiq90/Documents/github/buildtest/var/report.json is a file or run a test via 'buildtest build' to generate report file
