Pyyaml 5.4.1-6.0.0 has broken half the python eco system about taskcat

[shadycuz]

@andrew-glenn Yes this fixes the issue where pip has to download many versions of the same package looking for an older version that has the same pyyaml requirements as taskcat. This makes it much easier to install taskcat along side other python projects that also depend on pyyaml.

I'm also getting the same error while installing taskcat on python 3.10

Here's a temporary workaround
#803 (comment)

@andrew-glenn Hey, as anyone at AWS looked at this? When we try to install taskcat in our CICD pipelines, it ends up installing like 20 version of taskcat and then 30 versions of cfn-lint just to find a combination that works with pyyaml.

Now our builders run out of disk space once a week until we delete the docker cache.

I'll check this out first thing tomorrow.

@shadycuz Please install from source from my fork in #810; This sorts itself out locally, but I'd rather do this once.

Apologies for the delay in responding to this.

@andrew-glenn will give it a go in the morning. Thanks =)

@shadycuz circling back on this; Any luck ?
