Create Dockerfile to containerize billing script

[QuanMPhm]

Splitting up #15, and dependent on #20, as the next step before creating a fully automated cronjob to process invoices, we want to create a Docker container containing the bare dependencies needed to run the cloning and billing script.

@knikolla @naved001 As a solution I will create a Docker container with a shell script which does the following:

• Clone the non-billable repo
• Fetches the invoices for the previous month from S3 storage
• Passes all relevant files to process_report.py

@QuanMPhm And 4th step, uploads the generated invoices in the appropriately named way.

My questions/things I need so far are:

• I need access to a list of Old PIs. Where is that currently stored? @naved001 suggested that it should be placed in the nonbillable repo alongside other files that would impact billing.
• @joachimweyl @knikolla Since we want this Docker container to upload the processed invoices back to S3, what should be the naming convention for all the HU-only, HU & BU only, Lenovo-only, and the PI-specific invoices?

@QuanMPhm here is a list of the PIs.

The naming convention for the files should be

HU&BU - NERC-<YYYY>-<MM>-Total-Invoice.csv
Lenovo-only - Lenovo-<YYYY>-<MM>.csv
PI specific - <University>_<PI>_<YYYY>-<MM>.csv
HU-only - We no longer need this, HU pulls from HU&BU file

[QuanMPhm]

@joachimweyl If it's not a big problem, I'll have the file names be as follows:

HU&BU - NERC Total Invoice <YYYY>-<MM>.csv
BU Internal - NERC BU <YYYY>-<MM>.csv
Lenovo-only - Lenovo <YYYY>-<MM>.csv
PI specific - PI Invoices/<University>_<PI>_<YYYY>-<MM>.csv

It would just simplify the code if the invoice month (YYYY-MM) is consistently placed at the end of the filename.

Please make sure HU&BU is labeled NERC-<YYYY>-<MM>-Total-Invoice.csv as that is the file name MGHPCC requested. The others look fine.
