Expose bcrypt as part of argocd

[jsoref]

Summary

If bcrypt is an important component of how argocd works, and argo-cd (the project) doesn't believe everyone has easy access to bcrypt (I'm willing to believe this, although at this point, it might be possible to argue that everyone has python or even access to docker), then argocd (the program) should offer bcrypt as a command that can be run to do whatever is needed to perform a bcrypt.

Motivation

https://argo-cd.readthedocs.io/en/stable/faq/#i-forgot-the-admin-password-how-do-i-reset-it

To change the password, edit the argocd-secret secret and update the admin.password field with a new bcrypt hash. You can use a site like https://www.browserling.com/tools/bcrypt to generate a new hash.

One should never suggest a website for something relating to credentials. It's always the wrong answer.

Proposal

Add a argocd bcrypt that supports performing whatever action this series of steps imagines a user needs to do.

Disclaimer: At this point, I am not remotely certain these steps are meaningful as they certainly don't correspond to the structure of my instances.

At the very least, we should change the docs to recommend a binary install of bcrypt rather than a website.

@jannfis: Do you want to reopen this to cover #10056 (review)

[crenshaw-dev]

Yep, my bad, that PR didn't cover everything asked here.

[jannfis]

Yes, I actually merged the linked PR without looking at this issue.

I'm totally in favor of this enhancement proposal. Thanks.

[jannfis]

I'm not necessarily fond of exposing it as a first class top level command.

I think the right place where it should live is at argocd admin account - WDYT?

[jsoref]

If that's the only place that needs it, that sounds good.

(I wasn't trying to ask for a first class command, just a thing to cover whatever argocd needs users to use bcrypt to do)

I am working on this issue.
