lib/logger: limit the maximum arg length, which can be emitted to log lines 
This should prevent from emitting too long lines when too long args are passed to logger.* functions.
For example, too long MetricsQL queries or too long data samples.

* vmagent: add error log for skipped data block when rejected by receiving side

Previously, rejected data blocks were silently dropped - only metrics were update.
From operational perspective, having an additional logging for such cases is preferable.
