Pin awscli version on Ubuntu14

This is done in order to pin botocore to version 1.10.84 which
doesn't break the cloud-init package installed into the OS

The package version that need to be preserved is urllib3
awscli -> botocore -> urllib3
cloud-init -> urllib3

The version of the awscli from repository depends on an old version of
botocore that does not work with newest regions.
