vms-a22: Correct historical string measurements, which had wrong concatenations of strings

See comments in #439 for details

@rcavaliere I have the query to fix the measurements:

with newval as (
    select m.id, string_value
    from measurementstringhistory m 
    join provenance p on p.id = m.provenance_id 
    where p.data_collector = 'odh-mobility-dc-vms-a22'
    and string_value ~ '([0-9]+?\|)+?[0-9]+?'
) 
update measurementstringhistory m
set string_value = array_to_string(array(select distinct unnest(string_to_array(newval.string_value, '|')) order by 1), '|') 
from newval 
where m.id = newval.id;

This will create single numbers (as strings) or concatenation of numbers like 1|2, if we have more than one distinct number inside. The ordering of the number is not preserved, is that a problem? For example, 2|1 becomes 1|2 will always be sorted in a ascending manner.

@Piiit that's not an issue, we can proceed!

@rcavaliere Done, we updated 3661043 records...

Please test on production and eventually reopen this issue
