tensorboard=2.0 cannot start in Anaconda Distribution 2019.03

[mengxr]

Tensorboard 2.0 (dynamically) requires setuptools>=41 while Anaconda Distribution 2019.03 bundles setuptools=40.8. Shall we explicitly declare dependency "setuptools>=41" in tensorboard recipe so users do not need to run into this error by default.

$ docker run -it continuumio/anaconda3:2019.03
# conda install tensorboard=2.0
# tensorboard -h

Adding a run time setuptools >=41 requirement will enforce this requirement. I'll add it to the recipe and create new packages.

[jjhelmus]

The existing tensorboard packages have this new requirement hotfixed in as well.

Thanks @jjhelmus !
