ISPYB: Deposit robot load entry

[DominicOram]

With Hyperion starting to do the robot load we should be putting the robot load entry into ispyb.

Additionally, we would like to do this with the new ispyb REST interface, exp-eye.

Acceptance Criteria

• There is an ispyb callback to put the robot load data into ispyb
• There are sufficient tests for this

[DominicOram]

From looking at current collections it looks like:

• snapshot_after is actually a snapshot of the webcam view after robot load
• snapshot_before is actually a snapshot after load but from the OAV view

[DominicOram]

GDA actually starts the robot load entry, we just need GDA to pass in the id and we can finish it. See loads on https://ispyb.diamond.ac.uk/samples/sid/5054101

Note that we're not actually going to use this yet, see #1047 (comment)

[DominicOram]

#1055 contains a good start that whoever picks this up can run with but I don't think it's worth trying to get this in now so putting it on the backlog

[DominicOram]

FYI @gfrn. I started some work on this a month ago in the associated PR but dropped it for more urgent things. We would like to try again at some point in March but no fixed idea of when yet.

[DominicOram]

Ignore the snapshots part for now, will be done as part of #1282

[DominicOram]

Using existing python API we think S
Using new REST interface we think M

@DominicOram - work out which of these we use

[DominicOram]

Discussed with @NKatti2011, we should use exp-eye.
