Decision logging: confusing "upload chunk size too small" error message

[anderseknert]

When the size of a decision log chunk exceeds the size limit set by the upload_size_limit_bytes configuration attribute, an error message saying "upload chunk size too small" is printed to the logs. This is confusing to users, as arguably, the upload chunk size is too big, and the configured value is too small. Additionally, there's no indication as to what configuration attribute controls this, so it's not immediately clear what to do in order to fix this. A better error message could say something like:

"upload chunk size (81293) exceeds upload_size_limit_bytes (64000)"

I like the updated error message! That gives the user more context, and makes the problem a bit clearer.
