[Improvement]: Provide completions after providing the accessor of a resource method

[nipunayf]

Description

The current implementation does not provide the possible paths as completions for a given resource accessor. In some cases, it would be convenient for the user to have access to the paths associated with a given accessor.

Describe your solution(s)

Consider the following Ballerina example.

client class MyClient {
    resource function post first/[string param]/third () {}
    resource function post fourth/[string foo]/[int param2]() {}
    resource function put first/[string bar] () {}
    resource function get path() {}
}

function listAllPaths() {
    MyClient cl = new;
    cl->.p<cursor>
}

In the above syntax, it should provide all the available paths for the accessors that start with p, in this case, post and put.

@shafreenAnfar As of the current implementation, the user can enter the accessor along with the resource paths without the . to get the relevant resources. For instance, if the user needs to determine the resources with third as a resource segment to add, he can simply type thirdpost. Once the user enters the ., it creates a new completion request with a different context, which requires a complex implementation for the LS to provide the expected completions.
