Add Bytemark Hosting domains

[pcammish]

Specifically uk0.bigv.io, dh.bytemark.co.uk, and vm.bytemark.co.uk.

Bytemark Hosting provides both dedicated and virtual servers on the above domains, with customer host provided subdomains (and sub-sub domains) of the above.

Relevant TXT records should be along soon.

DNS is live for vm.bytemark.co.uk and dh.bytemark.co.uk:

$ dig +short TXT _psl.vm.bytemark.co.uk
"https://github.com/publicsuffix/list/pull/620"

$ dig +short TXT _psl.dh.bytemark.co.uk
"https://github.com/publicsuffix/list/pull/620"

The TXT record for uk0.bigv.io may take a while however, but email verification should be fine (although more hassle, sorry!)

I'm unable to verify that the TXT record exists

[pcammish]

Hi @sleevi, unfortunately due to the way the uk0.bigv.io DNS is served, it's not possible to generate TXT records for it, but if you email me to verify, I should be able to confirm it for you directly.

Many apologies for the hassle this causes.

Unfortunately, we are trying to require (persistent) TXT records for all new additions. This will prevent moving forward on this PR

[pcammish]

Hi @sleevi, thanks for the quick reply - I'll see if we can get some engineering time here to enable the serving of TXT records on the uk0.bigv.io domain.

[pcammish]

uk0.bigv.io has been removed for now to allow this to go through, but queries against dh.bytemark.co.uk and vm.bytemark.co.uk should be okay.

Once we have the technical issues resolved, I'll submit another pull with uk0.bigv.io included.

Verified
