upgrade to hbase 0.94.20 and do not support opentsdb 1.1 anymore
reinstate the default recipes used in the vagrant file
fix(attributes/default): use https github url to be proxy compliant
fix: specify dependency to yum 2.4.4 in cookbook metadata
feature: reinstate the Berksfile with the 2.x syntax (site instead of source)

build: ignore .awl files

- selfish but will prevent me to push unwanted files
feature: provide start scripts for hbase/tsdb/tcollector/all

- not yet the full init.d/systemd files, but usefull when the box is used outside of vagrant
feature: provide grafana install and setup
build: bump version
debug: extra debug for hbase table creation (wtf?)
added debug after 'create if needed' execution
feature: refactoring and tests to get every started as expected
feature: simplify guard launches of tsdb, hbase and create hbase table script + sleep 15s before trying to create hbase tables to let the hbase master finish its init
build: ignore .kitchen directory
feature(nginx): override the default recipe used to install nginx
quality(Vagrantfile): fix indentation of the chef.run_list lines
feature: use latest yum cookbook and adjust yum::epel to yum-epel accordingly

- also uniformised the usage of spaces around equals signs
feature: first integration tests
fix the base box used, use one provided by chef on vagrant cloud
definitely switch to Berkshelf for vagrant >= 1.5
