These correspond to properties that can be set in VMOD dynamic.
Currently we have:

dnsRetryDelay: this is set as the ttl in the VMOD. Since we get
DNS TTLs from the server, it effectively sets the retry delay
after a lookup gets negative results. More recent versions of the
VMOD have a separate parameter for this purpose, so this should be
updated soon.

domainUsageTimeout: corresponds to the domain_usage_timeout param
of the VMOD director.

firstLookupTimeout: corresponds to the first_lookup_timeout param
of the VMOD director.

resolverTimeout: set with the .set_timeout() method of the VMOD
resolver object.

resolverIdleTimeout: set with the .set_idle_timeout() method of the
VMOD resolver object.

maxDNSQueries: set with the .set_limit_outstanding_queries() method
of the VMOD resolver object.

followDNSRedirects: set with the .set_follow_redirects() method of
the VMOD resolver object.
