@Fedik, I've found that these options don't have corresponding envs:

• asset_id
• session_metadata_for_guest
• session_memcached_server_id
• feed_limit
• feed_email

Add support for them in your PR, please.

[Fedik]

asset_id probably can ignore, I did not found why it is needed.
Others I will update later.

[voronkovich]

@Fedik, I've just checked the Joomla source code and didn't find any usage of the asset_id. So, maybe you're right - it's a totally useless parameter.
