Detected field values: Response sometimes has space between digits and units, breaking queries #910
Description
Sometimes we get responses like this:
{"limit":1000,"values":["4.4 kB","568 kB","916 B","949 B","761 B","7.2 kB","865 B","1.7 kB","292 B","575 B","3.7 kB","17 kB","1.9 kB","866 kB","2.5 kB","2.1 kB","479 B","708 B","768 B","799 B","1.1 kB","79 kB","5.4 kB","3.2 kB","681 B","62 kB","596 B","921 B","297 B","3.3 kB","241 kB","6.4 kB","699 B","899 B","515 B","3.4 kB","550 B","2.7 kB","1.2 kB","432 B","1.5 kB","438 B","425 B","29 kB","5.2 kB","793 B","189 B","166 kB","38 kB","562 B","5.7 kB","175 kB","9.7 kB","0 B","13 kB","4.1 kB","654 B","3.1 kB","7.1 kB","30 kB","1.4 kB","409 kB","20 kB","7.6 kB","11 kB","1.8 kB","1.3 kB","504 B","2.6 kB"]}
And other times like this:
{"limit":1000,"values":["514B","116B","136B","154B","807B","908B","642B","775B"]}
Currently the spaces before the unit is making it into the query, which breaks the query as that is not valid logQL.
Please strip out white-spaces before the units and bring up to Loki folks to make sure this isn't a bug Loki side.
