DOC: Removed references to v0.17 in docs and doc strings
- [ x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

This PR removes references to changes and "versionadded" for pandas v0.17. This can be considered a continuation to #17504.

I propose pulling this in as soon as 0.21 is released.

Alternatively, these could be accepted in v0.21, as these references to v0.17 IMO are too old to be useful to the average doc reader (approx. 2 years) and upgraders could just reference the 0.20 docs or the whatsnew sections of v0.21.

 @bkmrkr Please stopping spamming our github issues. As already noted to you twice before, you have to do this yourself. Follow the link to see this issue online on github, and at the top of that page you will see somewhere an "Unwatch" button, with which you can stop watching the pandas project. we can do this after 0.21 Ok to version later than V0.21.

I've made the change requested by @jorisvandenbossche .

In addition, I've found a reference to v.013 in ``io.rst`` that I *think* should be removed, could you take a look at that (*maybe* it's talking about changes later than c0.13 also; in that case the text should be made more explicit).  can u rebase  I've rebased. @topper-123 Thanks!
