added bash script to automate jules kgo process.

Description

Automate jules kgo process found here: https://code.metoffice.gov.uk/trac/jules/wiki/KGOInstall

Script copies from user directories on azure spice and ex machines to the kgo locations on those machines.

Have tested with dummy directories in the appropriate places but would be a good idea to test with an actual install to ensure it has the intended behaviour.

TODO: Future proof by separating out ex into variables

[ericaneininger]

General comments while this PR is still in draft...

• This script could do with some future proofing. It WILL be run on machines other than EX and potentially other than AzureSpice
  • Keep absolute paths out as far as possible – they will probably change
  • Keep machine specific stuff together as far as possible
  • Stick to generic variable names if possible
• The final exit (in particular) is unnecessary and may well cause the user's shell to close (irritating). I assume this is here because the original script xsudo'ed as julesadmin and then exited as that user.
• Nested "" are best avoided as they are confusing to read. An alternative way to delimit environment variables would be ${VARNAME}
