update version

adding config directory

A configuration directory can be filled with yaml files that will be read by vault-ctrl-tool.
Each of those files will be concatenated so some issues must be considered.
The main vault-config.yml file set the version and that cannot be change in one of the yaml in the config directory.
Vault-ctrl-tool will read the first depth in the config directory, so sub-directories will be ignored.

New sidecar behaviour and Prometheus server toggle-able

• Features and changes added in 1.3.0 can now be toggled

Sidecar mode no longer terminates on failures

v1.3.0: 22-Nov-2021

• Errors during sync loop while running sidecar mode will no longer terminate vault-ctrl-tool.
• Sidecar mode now can run a Prometheus metrics endpoint which emits metrics about sidecar syncs.
  Prometheus can be toggled with "--enable-prometheus-metrics" and have its port overridden by "--prometheus-port".
• Added better documentation and some refactoring and cleanup of internal libraries.
• Vault client HTTP timeout and maxRetries are now configurable using "--vault-client-timeout" and "--vault-client-retries" flags.
  Note: These now default to 30s and 2, respectively. Compared to previous version of vault-ctrl-tool which where 60s, 2.
