task: extend WAII to support Apache IoTDB as a data store backend

[slawr]

Extend WAII to support the Apache IoTDB embedded DB as a data store backend.

Work breakdown:

• Add IoTDB to WAII State Storage component

[slawr]

Initial IoTDB integration into WAII completed.
Pull request to add the support to the Playground here #20
Upstreaming of the code is being tackled in an separate issue #19 as it will likely have a different timeline

[slawr]

Discussion was ongoing upstream about merging but upstream maintainers have taken decision to merge as they wish to close all PRs before moving from W3C to Covesa infrastructure.

Some tasks were identified in the discussion. For example:

1. WAII documentation should be extended to document Apache IoTDB use, including runtime requirements
2. Support for IoTDB in WAII feeders needed if they are to be used.

Decision needed whether to track this here or to create separate issues.

[slawr]

Documentation has been added.
Took the decision to support IoTDB in WAII feeders as a new separate issue as it is not strictly required here.

Upstream WAII project has merged the following PR's covering IoTDB:
Documentation: COVESA/vissr#2
Runtime config: COVESA/vissr#5
Add get/set support: w3c/automotive-viss2#110
