azure-cli: Permission Denied on PKG-INFO file of azure_cosmos package

@nrobert The azure-cosmos package is upgraded in this PR and is targeted to be released on August 25 with 2.11.0.

This also occurred for me on azure-cli 2.9.1 on macOS 10.15.6 installed with Homebrew 2.4.8.

The installation was performed using a different user account (with administrator privileges) than the user who is running the az command. (Although it’s not technically about administrator rights per se, it’s about the files below being owned by the installation user and unreadable by anyone else.)

Other files in /usr/local/Cellar/azure-cli/2.9.1/libexec/lib/python3.8/site-packages/ have the permissions set to -rw-r--r-- (0644), but the following files are set to -rw------- (600):

% cd /usr/local/Cellar/azure-cli/2.9.1/libexec/lib/python3.8/site-packages    
% find . -perm 600
./azure_cosmos-3.1.0-py3.8.egg-info/PKG-INFO
./azure_cosmos-3.1.0-py3.8.egg-info/SOURCES.txt
./azure_cosmos-3.1.0-py3.8.egg-info/requires.txt
./azure_cosmos-3.1.0-py3.8.egg-info/top_level.txt
./azure_cosmos-3.1.0-py3.8.egg-info/dependency_links.txt

One or more of these files are attempted to be read upon running az, so therefore no user other than the installation user can execute az unless these permissions are manually changed.

Same problem on my side since updated Python to 3.8 and az-cli, with brew
