Suggestion for adding function for proxy configuration for connector of Confluence-V6

Hi there,

Currently, I am having a problem regarding the need for proxy information to connect to Confluence Cloud (SaaS) from the Confluence connector.
As you know, we can use Confluence Server (self-built environment) or use Confluence Cloud (SaaS).
Using Confluence Server, you can set up a server (for example, located in the same place where ManifoldCF is running) so you may not need to use proxy information for the connection.
However, for Confluence Cloud (SaaS), there will be cases where you need to set proxy information to be able to connect.

I have checked in a few other connectors of ManifoldCF, there are a few connectors that support setting proxy information for the connection, for example: SharePoint, Jira, Slack, ...
Therefore, I would like to suggest editing Confluence-v6's sourcecode (including Authority connector and Repository connector) so that we can have an option to set proxy information to use for connection to Confluence when needed.

Connector Name

• Confluence-v6 (including Authority connector and Repository connector)

Improvement Detail

• At the Confluence connection setting screen, add fields that allow the user to set proxy information (eg: proxyProtocol, proxyHost, proxyPort..).
  The proxy setting screen will look like below:
  

• When connecting (call method `connect()`), use the set field values as proxy information.

※ This improvement applies to both the Authority Connector and the Repository Connector side.

Suggested source code (based on release 2.22.1)

Because the content is edited in many files and the number of LOC is quite large, I will attach the patch file here, please check it.
