Feature:
Pcs command `pcs property` is now able to export cluster properties configuration in form of text, json and pcs command(s) by using option '--output-format'. New command `pcs property defaults` for displaying default values of cluster properites was added. Another new command `pcs property describe` for describing meaning of cluster properties was added. Text format output of `pcs resource describe` command was extended and unified with `pcs property describe` text output.
Reason:
Pcs was able only to export configuration of cluster properties in text format. Ability to export configuration of cluster properties in format of pcs command is very useful feature that contributes to more portable form of re-creation of current cluster configuration. In order to add feature, the `pcs property [config]` command needed to be rewritten to the new architecture.
Result:
Pcs command `pcs property` now support '--output-format' option. There are 3 formats of output available: 'cmd', 'json', 'text', default is 'text'. The 'text' format has not changed from previous `pcs property` command plaintext only format. Another two commands were added: `pcs property defaults` and `pcs property describe`. Text output format of `pcs resource describe` command was extended.
