Indicate to users created accounts will be subdomains

[kcole16]

Overview

Once near/nearcore#2292 lands, near-shell should indicate to users that near create_account can only create:

• Subdomains of the sending account --masterAccount
• TLDs with >= 11 characters.

Example:
Using kendall.near, I can create accounts like test.kendall.near and hasatleasteleven.

It seems that top level account names that are longer than 11 characters will still be allowed.

We bumping account names that are allowed to 32 characters FYI.

I'm getting CreateAccountNotAllowed when I am trying this. Is this just disabled on testnet and fixed in the linked nearcore issue?
This was for creating a TLA:

@mikedotexe well, hihihihihihi.test is unfortunately not a TLA.

Darn, we need to reopen this and fix some issues Vlad saw this dev-deploy. My mistake for not catching it.
