adding wildcard feature

Reference issue

Resolve #99

What does this implement/fix?

Support for adding multiple configs at once, e.g.:

seml experiment add config0.yaml config1.yaml
seml experiment add *.yaml

I checked out the code and tried it in the example directory and got the following:

seml/examples$ seml seml_test add *.yaml

Hi, should work now.

Further fixes:

• cleaner way of changing directory by using a context manager
• clean up: drop collection after deleting all experiments

[n-gao]

Source code reloading does not work properly because the function signatures changed:

Traceback (most recent call last):
  File "/nfs/staff-ssd/gaoni/miniconda3/envs/seml_test/bin/seml", line 33, in <module>
    sys.exit(load_entry_point('seml', 'console_scripts', 'seml')())
  File "/nfs/staff-ssd/gaoni/repos/seml_scholten/seml/main.py", line 298, in main
    f(**vars(command))
  File "/nfs/staff-ssd/gaoni/repos/seml_scholten/seml/manage.py", line 445, in reload_sources
    check_config(seml_config['executable'], seml_config['conda_environment'], configs)
TypeError: check_config() missing 1 required positional argument: 'working_dir'

Do we still need the explicit working_directory in the reload_sources function if we pass it downstream?

LGTM, thank you! Closes #99
