Support of plain HTTP proxy

[kvendingoldo]

Describe the solution you'd like tfswitch support --mirror command that can be used with local proxy. E.g.: ["tfswitch", "--mirror", "https://localhost-archive/mirror/terraform", "--bin", f"{os.getcwd()}/bin/terraform"]

Looks like that it should work via TFENV_REMOTE, but we have to check HTTP compatibility.

Setting a value for on of the <TOOL>_REMOTE env var change the behavior of tenv, because it is considered that the user will access an http proxy to download artifact.

However tenv still call api (github or hashicorp) to list those artifact. do you think it would be better to change the default proxy mode ? (list from the proxy when <TOOL>_LIST_MODE is not forced to "api")

I think yes, it's more obvious way. WDYT?
