MySQL table_open_cache size unusually small

https://bugzilla.redhat.com/show_bug.cgi?id=1080547
Users do not have the ability to change table_open_cache to values other
than 4 (and have them stick).  The set value seems too low to allow
database operations to remain efficient.  For example, in my app I have
18 tables that are constantly being written to from a single persistent
connection, but can only have four tables cached at a time.  This leads
to tables having to be re-opened which causes fairly significant disk
I/O.

util: add nodejs context for bundle exec call

Bug 1030873
https://bugzilla.redhat.com/show_bug.cgi?id=1030873

NodeJS needs to be available for `bundle exec` call in `ruby/lib/util`
since it triggers asset compilation

Ensure modified confs are replaced during upgrades

Version specific ERB files should be copied during setup rather
than install; otherwise, new conf files will never be copied
to the live cartridge conf directory during upgrades (as install
is only called once during the life of the cart, whereas setup
is invoked during install/upgrades but prior to ERB processing).
