Add a tool to visualize the tasking system

ref: https://issues.redhat.com/browse/PULP-241

This is looking good. Can you give a docs example of running a full command against staging and prod also please? Obviously the cert and key references won't be right, but the command generally would be. Thanks!

@git-hyagi I went to run this just from the CLI (no container). I run this command python tasks-cli.py -c ~/Documents/Redhat/bmbouter-crc.crt -k ~/Documents/Redhat/bmbouter-crc.key --base_address https://mtls.internal.console.redhat.com and I get this TB:

Traceback (most recent call last):

Can these have literal addresses for the proxy and stage host?

[bmbouter]

Can this have the literal hostname to use for prod_host?

The graphs seem to be all zeros. When I run python tasks-cli.py -c ~/Documents/Redhat/bmbouter-crc.crt -k ~/Documents/Redhat/bmbouter-crc.key --base_address https://mtls.internal.console.redhat.com --period 3000 that's a lot of history and surely some tasks ran in that period. The output shows all zeros.
