Failure results in messy message leaking internals

[Mark Shuttleworth]

When unable to install a snap:

$ sudo snap install --classic --beta conjure-up
error: cannot install "conjure-up": Get https://search.apps.ubuntu.com/api/v1/snaps/details/conjure-up?channel=beta&fields=anon_download_url%2Carchitecture%2Cchannel%2Cdownload_sha3_384%2Csummary%2Cdescription%2Cdeltas%2Cbinary_filesize%2Cdownload_url%2Cepoch%2Cicon_url%2Clast_updated%2Cpackage_name%2Cprices%2Cpublisher%2Cratings_average%2Crevision%2Cscreenshot_urls%2Csnap_id%2Csupport_url%2Ctitle%2Ccontent%2Cversion%2Corigin%2Cdeveloper_id%2Cprivate%2Cconfinement: read tcp 192.168.1.105:49516->162.213.33.200:443: read: connection reset by peer

While failures will occasionally happen, the measure of our quality is how gracefully we handle them.

In this case, it would be much nicer to see something like:

$ sudo snap install --classic --beta conjure-up
error: cannot install "conjure-up": connection reset by snap repository

Also 'conjure-up' not "conjure-up". Use double-quote for quoted speech and single quotes for a term or a name, as in this case.

I'm marking this as confirmed since we still (as of snapd 2.27.2) show the full (ugly and long) URL we attempted to get when the network connection fails for some reason.
