cmd: env: add option for quiet output on env info
The "env info" can be use for test with -d and -p parameter,
in scripting case the output of the command is not needed.
This patch allows to deactivate this output with a new option "-q".
For example, we can save the environment if default
environment is used and persistent storage is managed with:
if env info -p -d -q; then env save; fi
Without the quiet option, I have the unnecessary traces
First boot:
Default environment is used
Environment can be persisted
Saving Environment to EXT4... File System is consistent
Next boot:
Environment was loaded from persistent storage
Environment can be persisted

This command can be optionally used for evaluation in scripts:
[-d] : evaluate whether default environment is used
[-p] : evaluate whether environment can be persisted
+ [-q] : quiet output
The result of multiple evaluations will be combined with AND.
