Summary0037113: Index clean up in C_Order table
DescriptionC_ORDER_DOCNO is not needed because C_ORDER_DOCUMENTNO_ID also indexes by DOCUMENTNO as first column.

In C_ORDER_CLIENT_ORG_DATE_DOCNO we can remove AD_CLIENT_ID column because in most of the cases all the orders in the system belong to the same client. This will reduce index size and will improve performance.

for 2nd index (remove ad_client_id) -> marked as related with issue where we did same change already in 2 other tables (for similar reason)

for 1st index:
- As both indexes are not unique functionally they are equivalent
- However for performance + size the 'single' column one is still better than combined one.

Example for but database with 84M orders:
- c_order_docno 2.592MB size
- c_order_documentno_id 6332MB size

Note: that combined one we need for grid ordering anyway

So in practice not just delete -> better but balance:
- is perf improvement for queries not needing _id part worth having the overhead of
- 2.5gb space + overhead of maintaining that idx

I tend to say not worth having both but don't have hard numbers ready.
