47748ef4b6 metadata-service: remove check for OpenStack meta_data.json 
The meta_data.json blob under OpenStack doesn't actually contain all
of the metadata... Fall back to explicitly requesting each attribute.

fae81c78f3 metadataService: Check both ec2 and openstack urls more explicitly 
Remove the root url parameter for -from-metadata-service since this
is a guarenteed value. Additionally, check for both ec2 and openstack
urls for the metadata and userdata. Fix a bug with the -from-url
option and a panic on an empty response.

361edeebc6 metadata-service: Add metadata-service datasource 
Move the old metadata-service datasource to url datasource. This new datasource
checks for the existance of meta-data.json and if it doesn't exist, walks the
meta-data directory to build a metadata blob.

ff70a60fbc Adds sleep cap to exponential backoff so it does not go too high 2014-05-15 13:04:37 -04:00

31f61d7531 Use exponential backoff when fetching user-data from an URL. 
The user-cloudinit-proc-cmdline systemd unit is responsible for
fetching user-data from various sources during the cloud-init
process. When fetching user-data from an URL datasource we face
a race condition since the network may not be available, which
can cause the job to fail and no further attempts to fetch the
user-data are made.

Eliminate the race condition when fetching user-data from an URL
datasource. Retry the fetch using an exponential backoff until
the user-data is retrieved.

Fixes issue 105.
