query: make $select true by default

The most outstanding concerns for $select query have been resolved. We
added a set of restrictions: character set, property length, # of
properties, which makes this feature safe to use.

This commit takes $select out of the insecure flag, so every system can
start to use it. This decision has been made in Discord, available at

Tested:
1. unit test passed
2. no new service validator failure on hardware
