Code Issues Proposed changes

Add config option reserved_share_extend_percentage

Browse Source 
'reserved_share_extend_percentage' backend config option allows Manila
to consider different reservation percentage for share extend
operation. With this option, under existing limit of
'reserved_share_percentage', we do not want user to create new share if
limit is hit, but allow user to extend existing share.

'reserved_share_extend_percentage' backend config option allows
Manila to consider different reservation percentage for share extend
operation.
This distinct option is useful if operators want to prevent provisioning
of new shares but allow extensions of existing shares on storage pools
beyond their reserved space.
