SOLR-14136: ip whitelist/blacklist via env vars
This makes it easy to restrict access to Solr by IP. For example SOLR_IP_WHITELIST="127.0.0.1, 192.168.0.0/24, [::1], [2000:123:4:5::]/64" would restrict access to v4/v6 localhost, the 192.168.0 ipv4 network, and 2000:123:4:5 ipv6 network. Any other IP will receive a 403 response.
Blacklisting functionality can deny access to problematic addresses or networks that would otherwise be allowed. For example SOLR_IP_BLACKLIST="192.168.0.3, 192.168.0.4" would explicitly prevent those two specific addresses from accessing solr.
User can now set SOLR_REQUESTLOG_ENABLED=true to enable the jetty request log, instead of editing XML. The location of the request logs will respect SOLR_LOGS_DIR if that is set. The deprecated NCSARequestLog is no longer used, instead it uses CustomRequestLog with NCSA_FORMAT.
Jetty 9.4.16.v20190411 and up introduced separate
client and server SslContextFactory implementations.
This split requires the proper use of of
SslContextFactory in clients and server configs.
This fixes the following
* SSL with SOLR_SSL_NEED_CLIENT_AUTH not working since v8.2.0
* Http2SolrClient SSL not working in branch_8x

Unfortunately, as a first start this is very weak protection against
e.g. XSS. This is because some 'unsafe-xxx' rules must be present due
to the insecurity of angular JS: Until SOLR-13987 is fixed, XSS & co are
still easy.
