Thanks Jiang Yan, there are acutally some discussion here 
https://reviews.apache.org/r/50677/ , the reason that I want to update this is 
because:
 
1) Make the code consistent, in the allocator test cases, some benchmark test 
using `OfferedResources` while some using `Allocation`, when people want to add 
new benchmark test, they will be confused: Which one shall I use, 
`OfferedResources` or `Allocation`, so here we need to make the code consistent 
with each other for better reading, easy to maintain and consistent.

2) Seems here using `OfferedResources` maybe better, as here we are actually 
constructing the `offers` on each agent; But the `Allocation` is an allocator 
concept and it means the resources for a specified framework. Also all of the 
log messages are highlighting `offer` in benchmark test such as here 
https://github.com/apache/mesos/blob/master/src/tests/hierarchical_allocator_tests.cpp#L3885

3) The benchmark test is focusing on `offers` even though the allocator know 
nothing about `offer`, but here we are just simulating `offer operations` in 
benchmark test. For other unit test cases other than benchmark test, they are 
focusing on `allocations` for each framework, so it is using `Allocation`. 

What do you think?
