New configuration option for interactive

[rafaelsteil]

What does this change accomplish?

Add a new configuration option to interactive and a command line argument to enable or disable automatic plotting when opening the UI.

Prior to that, anytime plotman interactive ran it would automatically fire any pending jobs, even before the user had the chance to press p to change its status.

This PR introduces two new options:

1. A new section in plotman.yaml
2. A command line argument

The section is tools/interactive/autostart_plotting, which defaults to True in order to keep backwards compatibility. The command line argument is --autostart-plotting and --no-autostart-plotting, which take precedence over `plotman.yaml``

How to test it

1. Set tools/interactive/autostart_plotting to False and later to True and check the interactive reflects the plotting status
2. Pass the command line arguments and check if they override what was set on the configuration file
3. Remove tools from the configuration file and run plotman interactive. It should show plotting as active (the original behaviour)

Hey @rafaelsteil, thanks for jumping in and getting this going. I have definitely wanted this myself in various senses. There should be a similar option for archiving. It could fit in this same PR if you want. Or we could handle it separately afterwards.

Take a look at BooleanOptionalAction in https://docs.python.org/3/library/argparse.html#action. I think this can be a single added argument.

Ok, so I think we can do it like this. Setting the dest to the same name on both let's them override each other which I believe is 'normal' cli behavior. It also eliminates any logic needed to process the results later.

import argparse


parser = argparse.ArgumentParser()
parser.add_argument('--x', action='store_true', dest='x')
parser.add_argument('--no-x', action='store_false', dest='x')

print(parser.parse_args([]).x, False)
print(parser.parse_args(['--x']).x, True)
print(parser.parse_args(['--no-x']).x, False)
print(parser.parse_args(['--x', '--no-x']).x, False)
print(parser.parse_args(['--no-x', '--x']).x, True)

False False
True True
False False
False False
True True

Slight update to account for the not-passed case so we can use the value in the config file.
