Additional parameters for Tree API - Sort, filterBy

Please introduce two additional parameters to the Tree API

I. sort by and sort type

• The sort by can accept the field on which the sort needs to be performed.
• The sort type can be 'ascending'/'descending'
• The pagination usecase would honor the sort fields.

II. filterBy

Add the support to filter the content based on a field and its corresponding value. The immediate usecase is 'ability to filter the tree object from the result, similar to git ls-tree -r HEAD behavior'

Adding the following for reference :)

Hi

Posting this issue here as requested from gitaly team.

We are using Gitlab API for one of our application and I'm trying to understand the sort key that is used by gitlab to get all the tree entries in the /projects/:id/repository/tree API.

git ls-tree -r     

OR

git ls-tree -r -t

is the behavior that I'm expecting from this web api, but it is returning the following with an internal sorting.

git ls-tree -r -t 

1. Could someone explain what's the exact sorting that is used by the api on tree entries list.
2. Would it be possible to add support for an additional request parameter for the following git ls-tree behavior.

git ls-tree -r     

Thanks,

Narayan
