revamp "move .conda" page

[craigsteffen]

Completely remove the description of moving your .conda directory. Add an explanation that filling up home quota doesn't have a universal solution.

Add one section on conda suggesting that users run "conda clean" when they're installing stuff in conda.

In the last couple of weeks, I attempted to do a move on behalf of a user, and had it blow up catastrophically on me. I asked the user in the ticket, and they were fine rebuilding their conda from scratch, so it wasn't a problem. But I really think the instructions for moving your .conda directory (which I thought was fairly robust and certainly didn't think would fail in a bad way) need to go away.

I've put instructions here to run "conda clean" per Robert Brunner, which I hope will at least help the people who fill up their home quotas with conda.

I'd like to get this merged soon-ish. Thanks.

Would you be willing to keep the “rsync” method but just put at the end as “this might work but use at your own risk” ?

OK with me, Craig?

@Greg Bauer
So you're proposing that instead of removing the method as I've put in the PR, to instead copy the exact method that JD wrote in the ICC page with a warning that says something like "this will probably work but it has been known to fail if the file system experiences slowness" or something like that?
Sure, I'm fine with that. If that's your proposal I'll rework the PR to say that. I'd also like to keep a collection of "this is how you keep software packages from filling up your home dir"; I believe, Greg, you'd advocated for that before anyway.

I believe Weddie and JD vetted the original rsync method that is currently documented on ICC and Delta.

So let’s have it as a last resorts option

A. Keep your home dir clean
B. Learn to install in other locations
C. if all else fails relocate your .conda
