Alfredo Moralejo 1d32e734f3 Retry calls to nova API when connection errors are detected

Currently, when a call to the Nova API fails for any connection
temporary issue, Watcher actions fail.

This patch is adding retries to nova api calls when connection issues
are detected. The retries can be configured with new parameters in the
nova section:

- http_retries (default is 3 retries)
- http_retry_interval (default is 2 seconds).

Note that, in order to implement the retries in all the nova_helper
methods, in some cases i am adding new elementary calls which are called
by more complex ones.

Closes-Bug: #2133934

     Resolve failures caused by temporary connection errors to Nova by adding
     configurable retries to Nova API calls when connection related errors are
     found. The retries can be configured via `[nova] http_retries` (default is
 retries) and `[nova] http_retry_interval` (default is 2 seconds).
