Fix Python package name

[jooola]

Many packages names needs fixing and should follow our naming convention.

The python module should not be libretime.api. The java script package should not belibre_time_api.

The Javascript client needs some investigation, as it ignores the package name parameter passed to it

Suggestions for the python module? libretime.client?

[jooola]

I would prefer not to lock the libretime module/namespace yet, maybe something like libretime_sdk or libretime_client, or even libretime_api_client and we rename the one in the repo to libretime_legacy_client ?

[paddatrapper]

What is holding you back on using the libretime namespace?

[jooola]

Because the generated python module at libretime is actually a module and not a python namespace. If someday we want to start using python namespaces, installing the api client module will prevent this from working.

EDIT: And it isn't consistent with the rest of the python packages we have.

I'm happy with libretime_client then
