Ben Nemec 7e79f319a8 Add release note for file descriptor limit change
This could have an operator impact, so we should mention it in the
release notes. See c0a86998203315858721a7b2c8ab75fbf5cd51d9 for the
actual implementation of the feature.

features:
- |
A configurable limit on the number of file descriptors that can be opened
by a rootwrap-started process has been added. It defaults to 1024, but
can be adjusted by setting the ``rlimit_nofile`` option in rootwrap.conf
to a larger or smaller value.
upgrade:
- |
Because a file descriptor limit was added in this release (see the features
section for details), rootwrap processes that were previously relying on
inheriting their parent process's descriptor limits may exhaust their
available file descriptors. Use the ``rlimit_nofile`` option to restore
the previous limits if this is the case.
