Log panel entries does not highlighted with filter by %word%

[up-to-you]

Is your feature request related to a problem? Please describe.
Log panel entries does not highlighted with filter by %word%.
For comparison - in Loki filtered by regex words are highlighted in Log panel.

Describe the solution you'd like
Because the name for the input variable may differ, it's reasonable to make setting where developer can enter variable name. Then, highlight words from variable input on the client side.

Sample:
client-side: $WORD_FILTER = 'error'
sql: where message ilike '%$WORD_FILTER%'
client-side: highlight error entries in log line

Describe alternatives you've considered
Maybe the solution Loki use for this purpose
