simplify connection to onelake Rest catalog

Feature Request / Improvement

currently to connect to onelake Iceberg Rest Catalog, you use something like this, which seems to have a lot of redundancy

from   pyiceberg.catalog import load_catalog
catalog = load_catalog("onelake", **{
    "uri"                       :                   onelake_endpoint, 
    "token"                     :                   os.environ.get('AZURE_STORAGE_TOKEN'), 
    "warehouse"                 :                   f"{ws}/{lh}.lakehouse",
    "adls.account-name"         :                   onelake ,
    "adls.account-host"         :                   f"{onelake}.blob.fabric.microsoft.com" ,
    "adls.token"                :                   os.environ.get('AZURE_STORAGE_TOKEN') ,
})
catalog.list_tables(schema)

in an ideal world, something like this will be nice

from   pyiceberg.catalog import load_onelake
catalog = load_onelake(warehouse_path)

we shouldnt add any vendor specific logic into the repo

you can achieve the same result using the .pyiceberg.yaml file
https://py.iceberg.apache.org/configuration/#rest-catalog

catalog:
  onelake:
    uri: ...
    adls.account-name: onelake
    adls.account-host: onelake.blob.fabric.microsoft.com

and do catalog = load_catalog("onelake", **{<extra configs>})
