Describe the bug
Cloning Web Maps with many layers in ArcGIS Online notebook causes urllib connection pool errors. possibly due to many hosted feature views published from single hosted feature layers, or many hosted feature layers in the web maps, not sure.

To Reproduce
Steps to reproduce the behavior:

print('importing modules')
from arcgis.gis import GIS
import urllib3
from getpass import getpass

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

# Variables
source = GIS("home")
print(source)

target = GIS(url = r'https://tgt.maps.arcgis.com',username = 'tgt_usr',password = getpass())
print(target)

print('Ready to clone')

source_group = source.groups.get(source_group_id)
items_to_clone = source_group.content()

print(f'Source Group: {source_group.title}')
print(f'Source User: {source.users.me.username}')
print(f'Target User: {target.users.me.username}')

for item in items_to_clone:
    if item.type == 'Web Scene' or item.type == 'Web Experience' or item.type == 'Dashboard':
        print(f'Cloning {item.id}: {item.type}: {item.title}')
        try:
            new_items = target.content.clone_items(items=[item], copy_data=True)
        except Exception as e:
            print(e)
        for new_item in new_items:
            print(f'{new_item.id}: {new_item.type}: {new_item.title}')
