This isn't dishonest at all - in fact it's common practice when asking for a recommendation from someone whose time is valuable to give them a draft recommendation letter for them to change as they see fit. Since they get "final cut" on the letter (and you will not see what they end up putting in/taking out), there is nothing dishonest about it at all. It's a little awkward, but expect to get similar treatment when asking for recommendation letters for match, etc. etc.
The reason why it is not dishonest is because the person you send the draft to will change it if they disagree with any part of it. I would say the only negative thing about it is that it shows the person writing your rec values their time much more than your application - which could be reasonable, depending on how valuable his/her time is. Try to ask for recommendation letters from people who know you well and can write persuasively for you - otherwise your letters may all start to sound the same (since a lot of the original material will be coming from you).
