Bug 33050: Allow to specify quote char in runreport.pl

Bug 33050: Allow to specify quote char in runreport.pl

Add to script misc/cronjobs/runreport.pl quote char arg (only for CSV).
See perl doc https://metacpan.org/pod/Text::CSV#new

This patch also adds missing '--separator' in POD.

Test plan :
1 - Write a SQL report
2 - perl misc/cronjobs/runreport.pl --format csv 1 (or correct report number)
3 - Note you get double quotes
4 - Apply patch
5 - Repeat #2 - no change
6 - perl misc/cronjobs/runreport.pl --format csv --quote "'" 1
7 - Now it is single quote delimited
8 - perl misc/cronjobs/runreport.pl --format tsv --separator "'" 1
9 - Error is reported, you cannot set quote unless csv
10 - Try empty string as quote
