fscore: rollback trailing space trim (#7106)

Browse source 
Previous commit 201fd6de1e removed
trailing space trim from data read from file. But common practice is to
remove such trailing space. And it leaded to the authorization errors
for the major group of users.

In first place, this change must help to mitigate an issue with
kubernetes. When authorization information was read from Secret content.
Changes to the operator was made to mitigate such problem at commit
1cf64358c8

We could introduce later optional flag for VictoriaMetrics to disable
trim space behavior.
