## Description

During Elasticsearch boot, users get the following message:

> license mode is [trial], currently licensed security realms are [reserved/reserved,file/default_file,native/default_native]

Even if it's technically true (and necessary), it may be confusing for end users since they may expect `[basic]` instead.

## Proposal

Avoid the message reporting the trial license, since the "correct" license level is written again later in the boot process.
