These keys are not managed by trust of a certificate authority, just by
"trust of first use" so it does not make sense to use a key authority.

This also cause difficulties to publish the key fingerprint as a
parameter, because we can't get the key fingerprint until the authority
service is started.

Also enable ecdsa key.

Existing webrunners will have a new ssh host key after this.

This reverts commit 2c5c1147.

This enable vieiwing applications logs directly in grafana, as long as
loki agent can access the log file and the regular expressions to parse
the logs are defined

Other changes:
 - provision data sources automatically so that user do not have to add
   them manually
 - update TODO in README
 - introduce a SR test
 - switch to dep to install dependencies, because that's how these
  packages manage their dependencies.

Versions up:
  grafana: v6.3.0
  telegraf: v1.11.1-0
  influxdb: v1.7.8rc1
New:
  loki: v0.3.0

This promise check if nextcloud app was correctly deployed, it ensure that slapos instance will deploy until nextcloud install succeed.

The called python program is python3 program, and provided
PYTHONPATH is from python2, resulting in bad behaviour.

On testnodes, python can be too long for linux shebang (#!) line.

We had for example:
    
    /srv/slapgrid/slappart15/srv/testnode/cqc/inst/test0-0/tmp/shared/python2.7/338ccc0e387d64185920266f8a97c87b/bin/python2.7
  

that is 123 characters long.

With this, the generated glib-genmarshall script will have:
    
    #!/usr/bin/env  /srv/slapgrid/slappart15/srv/testnode/cqc/inst/test0-0/tmp/shared/python2.7/338ccc0e387d64185920266f8a97c87b/bin/python2.7

which exceeds the linux kernel limit.

Instead, we generate scripts that will use
    
    #!/usr/bin/env python

and it will be the caller responsibility to set $PATH to use the expected python.


This fixes the issues we had on SlapOS.SoftwareReleases.IntegrationTest tests since we updated glib to 2.56.4 in a7a86db9

installing vscode-ripgrep creates a folder in temporary directory, but
never removes it.

On our test nodes it was observed that a first testnode running installs
and create this folder in /tmp/ then another testnode running as another
unix user installs and we had this error:
