### Motivation and Context
**1. Add default parameter values for available functions on Plan
creation (ActionPlanner)**

- This commit changes the `PopulateList` function to include the default
value of each parameter in the generated string. This makes the list of
available functions more informative and helpful for LLM to know the
default behavior of a function. The default value is shown in
parentheses after the parameter description.

- This is helpful in parsing the correct server-url for OpenAPI
functions (before, the planner was suggesting arbitrary values that were
more-than-intermittently wrong).


**2. Add support to override the server-url from user input**

- User input is passed as customer variable in Ask context when SK is
invoked in the format {openApiSkillName}-server-url
- This can then be parsed in the `SemanticKernelController` and passed
to the Import method
i.e., 
```
if (openApiSkillsAuthHeaders.JiraAuthentication != null)
        {
            this._logger.LogInformation("Registering Jira Skill");
            var authenticationProvider = new BasicAuthenticationProvider(() => { return Task.FromResult(openApiSkillsAuthHeaders.JiraAuthentication); });
            var hasServerUrlOverride = variables.Get("jira-server-url", out string serverUrlOverride);

            await planner.Kernel.ImportOpenApiSkillFromFileAsync(
                skillName: "JiraSkill",
                filePath: Path.Combine(System.IO.Directory.GetCurrentDirectory(), @"Skills/OpenApiSkills/JiraSkill/openapi.json"),
                authCallback: authenticationProvider.AuthenticateRequestAsync,
                serverUrlOverride: hasServerUrlOverride ? serverUrlOverride : null
                );
        }
```

3. Adds missing user-agent parameter to all ImportOpenApiSkill methods
for consistency
