Document production deployment steps

[joewiz]

• conf.xml (and other configuration files) for master vs. slave instances
• nginx.conf for web servers
• where each secret needs to be entered for API calls and Ant scripts to function ( Modify build target build-xar #54)
• how to connect to master to run app deployment steps

The README.md at https://github.com/18F/hub/tree/master/deploy could be a good model for this.

As noted in the hsg HipChat room in discussion with @HistoryAtState/existsolutions, this also needs to be documented:

• wrapper.conf (esp. memory settings)

Also:

• remember to update monex's instances.xml file with any new jmxservlet.token tokens from webapp/WEB-INF/data

Note that in #37 I added a facility to our ant scripts to apply an XSLT stylesheet to conf.xml - to enable the cache module and register jobs. See https://github.com/HistoryAtState/hsg-project/blob/master/build.xml#L765-L778 and https://github.com/HistoryAtState/hsg-project/blob/master/build/configure-exist.xsl#L15-L39.

While many of the requested items in this issue are already documented in hsg-configs, I'll keep this open as a reminder to myself to document as much of this as possible publicly.
