set default tqdm.disable from os.environ

[kaivalyar]

Allow setting the tqdm.disable option from the environment variables. The default value of False is unchanged, as is the expected behavior with None.

Resolves issues laid out it #619 #614 #612. Similar to the request in #370.

Less important but also useful:

  read the known issues

• I have mentioned version numbers, operating system and
  environment, where applicable:

  import tqdm, sys

This would be helpful for my use case, where I'm using a third-party library which has a tqdm bar I'd like to disable but can't modify the library code itself easily.

[kaivalyar]

Yes, this is exactly where I ran into this issue. I'm using pgmpy, which displays it's loops using the default tqdm behavior, which I would like to disable.

Looks like this PR has been open for quite some time. @casperdcl Any thoughts on this change?

A simple use-case for this option is that we are running a big set of code where we have both support to run the exact same code as a cli tool from a users computer and in a hosted environment inside celery. And when we run it in celery, we do not want our logs to be polluted with tdqm loggin output. This option would make it super easy to disable all tdqm logging as we have it in a lot of places in our code and we would just configure our production servers with this environment variable and we are all set.

Any updates on this PR? This is very useful when running tests and in production.

Thanks everyone for your patience! Just released tqdm==4.66.0 which includes support for env var overrides. I'm using TQDM_MININTERVAL=5 in most of my CI jobs now :)
