fix(yahoo): YF_QUERY_HOST in URLs (user configurable, default query2)

[gadicc]

Closes #95.
Closes #426.

Maybe a WIP for #95 or perhaps full first part of it that we could merge now.

• In modules: use URLs like https://${YF_QUERY_HOST}/blah
• In modules: avoid template literals to add ${query}
• In yahooFinanceFetch: do variable substitution, randomly picking between query1 / query2
• In fetchDevel: standardize to query2 for cache
• Substitute query2 in all existing tests/http files (query1 was much less common)

[gadicc]

May also be better to just have a default single YF_QUERY_HOST and let the user change it as desired, rather than picking randomly on every request, which could make it harder to find errors if one host starts acting up.

Just a note here, in the end, I didn't randomize the host, because:

1. That will be much harder to debug
2. It was pointed out that query1 is HTTP/1.0 and query2 is HTTP/2.0
3. So we default to query2 but allow the user to change it.
