By default don't initialize hooks when enabling and disabling plugins programmatically

[rtibbles]

Summary

• To do a full disable or enabling of a plugin, we also register all the hooks.
• This is appropriate from the CLI as it gives us warning of whether a hook registration does forbidden calls and initialization
• When enabling and disabling plugins programmatically, it can prematurely register a hook within the life cycle of an application using Kolibri
• Adds an extra argument to toggle hook initialization, which defaults to True
• Turns it off by default for the enable_plugin and disable_plugin functions
• Turns it on by default for the CLI invocation of enable_plugin

Reviewer guidance

Open a python shell and do the following:

from kolibri.core.hooks import RoleBasedRedirectHook
print(list(RoleBasedRedirectHook.registered_hooks))

from kolibri.main import disable_plugin
disable_plugin("kolibri.plugins.learn")

print(list(RoleBasedRedirectHook.registered_hooks))

With this PR, both print statements will produce empty lists. Without it, the second will produce a list like this: [<kolibri.plugins.learn.kolibri_plugin.LearnRedirect at 0x7feaa74dd8d0>]
