Bugfix/gh 218 nfs client

[laurentganne]

Pull Request description

Description of the change

Including in the tosca components zip bundled within the orchestrator a fix for the NFS client mount of the NFS server exported file system addressed in the Forge by fix for ystia/forge#38

In addition, added in versions.yaml the Alien4Cloud version that the bootstrap will download from Alien4Cloud public site by default (the user can define a download URL if he doesn't want to use the default one).

Previously this version was deduced from the versions of a4c forge components bundled within Yorc for the bootstrap, but it's better to not have this dependency so that:

• the version in versions.yaml and installed on bootstrapped infrastructure can follow deliveries of A4C milestones
• the version of TOSCA components within the zip bundled in Yorc and used by the bootstrap process only, can be updated when necessary (mainly, to take into account a4C forge components bug fixes impacting the bootstrap)

How to verify it

On a CentOS 7 compute instance created on google cloud,
donwload a Yorc from this pull request build.

Create a file input_values.yaml with the following content.
Warning: before the merge of ystia/yorc-a4c-plugin#75 taking care of making the plugin compatible with A4C 2.1.0-RC1,
you need to use the plugin from this plugin pull request for the bootstrap, by adding these lines to the values file:

yorc_plugin:
   download_url: https://dl.bintray.com/ystia/yorc-a4c-plugin/snapshots/feature/GH-196-a4c-sm7-jobs-enhancements/alien4cloud-yorc-plugin-3.1.0-SNAPSHOT.zip  

It gives this input file, you have to update to specify your user and creds file:

yorc:
  private_key_file: /home/<myuser>/.ssh/<my private key>
yorc_plugin:
   download_url: https://dl.bintray.com/ystia/yorc-a4c-plugin/snapshots/feature/GH-196-a4c-sm7-jobs-enhancements/alien4cloud-yorc-plugin-3.1.0-SNAPSHOT.zip  
infrastructures:
  google:
    application_credentials: /path/to/<my-project Service Account key file>.json
    project: <my-project>
address:
  region: europe-west1
compute:
  image_project: centos-cloud
  image_family: centos-7
  machine_type: n1-standard-1
  zone: europe-west1-b
  metadata: "ssh-keys=<My user>:<my public key>"
  tags: a4c
credentials:
  user: <myuser>

Then bootstrap a HA deployment running :

./yorc bootstrap --values input_values.yaml --deployment_type HA

Description for the changelog

Bootstrap of HA setup fails on GCP, at step configuring the NFS Client component (GH-218)
