Add imports (#161)

## Problem

Add four endpoints of the `BulkOperationsApi`.

## Solution

Added the following four endpoints of the `BulkOperationsApi`:
1. `startImport(String uri, String integrationId,
ImportErrorMode.OnErrorEnum errorMode)`
2. `describeImport(Integer limit, String paginationToken)`
3. `listImport(String id)`
4. `cancelImport(String id)`

## Type of Change

- [ ] Bug fix (non-breaking change which fixes an issue)
- [X] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] This change requires a documentation update
- [ ] Infrastructure change (CI configs, etc)
- [ ] Non-code change (docs, etc)
- [ ] None of the above: (explain here)

## Test Plan

Added unit tests.

+# Imports
+## Start an import
+
+The following example initiates an asynchronous import of vectors from object storage into the index.
+
+```java
+import org.openapitools.db_data.client.ApiException;
+import org.openapitools.db_data.client.model.ImportErrorMode;
+import org.openapitools.db_data.client.model.StartImportResponse;
+...
+
+// Initialize pinecone object
+Pinecone pinecone = new Pinecone.Builder("PINECONE_API_KEY").build();
+// Get async imports connection object
+AsyncIndex asyncIndex = pinecone.getAsyncIndexConnection("PINECONE_INDEX_NAME");
+
+// s3 uri
+String uri = "s3://path/to/file.parquet";
+
+// Start an import
+StartImportResponse response = asyncIndex.startImport(uri, "123-456-789", ImportErrorMode.OnErrorEnum.CONTINUE);
+```
+
+## List imports
+
+The following example lists all recent and ongoing import operations for the specified index.
+
+```java
+import org.openapitools.db_data.client.ApiException;
+import org.openapitools.db_data.client.model.ListImportsResponse;
+...
+
+// Initialize pinecone object
+Pinecone pinecone = new Pinecone.Builder("PINECONE_API_KEY").build();
+// Get async imports connection object
+AsyncIndex asyncIndex = pinecone.getAsyncIndexConnection("PINECONE_INDEX_NAME");
+
+// List imports
+ListImportsResponse response = asyncIndex.listImports(100, "some-pagination-token");
+```
+
+## Describe an import
+
+The following example retrieves detailed information about a specific import operation using its unique identifier.
+
+```java
+import org.openapitools.db_data.client.ApiException;
+import org.openapitools.db_data.client.model.ImportModel;
+...
+
+// Initialize pinecone object
+Pinecone pinecone = new Pinecone.Builder("PINECONE_API_KEY").build();
+// Get async imports connection object
+AsyncIndex asyncIndex = pinecone.getAsyncIndexConnection("PINECONE_INDEX_NAME");
+
+// Describe import
+ImportModel importDetails = asyncIndex.describeImport("1");
+```
+
+## Cancel an import
+
+The following example attempts to cancel an ongoing import operation using its unique identifier.
+
+```java
+import org.openapitools.db_data.client.ApiException;
+...
+
+// Initialize pinecone object
+Pinecone pinecone = new Pinecone.Builder("PINECONE_API_KEY").build();
+// Get async imports connection object
+AsyncIndex asyncIndex = pinecone.getAsyncIndexConnection("PINECONE_INDEX_NAME");
+
+// Cancel import
+asyncIndex.cancelImport("2");
+```
