Prior to this commit, Solr's Jetty listened for connections on all
network interfaces. This commit changes it to only listen on localhost,
to prevent incautious administrators from accidentally exposing their
Solr deployment to the world.
Administrators who wish to override this behavior can set the
SOLR_JETTY_HOST property in their Solr include file
(solr.in.sh/solr.in.cmd) to "0.0.0.0" or some other value.
Currently the documentation pretends to create a JKS keystore. It is
only actually a JKS keystore on java 8: on java9+ it is a PKCS12
keystore with a .jks extension (because PKCS12 is the new java default).
It works even though solr explicitly tells the JDK
(SOLR_SSL_KEY_STORE_TYPE=JKS) that its JKS when it is in fact not, due
to how keystore backwards compatibility was implemented.
Fix docs to explicitly create a PKCS12 keystore with .p12 extension and
so on instead of a PKCS12 keystore masquerading as a JKS one. This
simplifies the SSL steps since the "conversion" step (which was doing
nothing) from .JKS -> .P12 can be removed.
* SOLR-13984: add (experimental, disabled by default) security manager support.
User can set SOLR_SECURITY_MANAGER_ENABLED=true to enable security manager at runtime.
The current policy file used by tests is moved to solr/server
Additional permissions are granted for the filesystem locations set by bin/solr, and networking everywhere is enabled.
This takes advantage of the fact that permission entries are ignored if properties are not defined:

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.
The Overseer used java serialization to store command responses in ZooKeeper. This commit changes the code to use Javabin instead, while allowing Java serialization with a System property in case it's needed for compatibility
