LDEV-5204 Initiate canvas copy on tool content copy on back-end

In previous version canvas was copied when an user opened it. Sometimes

in LAMS we copy content without opening a canvas. For example when using

Save As or Copy buttons in Authoring. We had to make sure that canvas is

always either copied on back-end or it gets opened and copied via

front-end.

LDEV-5204 Introduce improved security using hashing

In vanilla Whiteboard a global access token is configured on server and

must be present in all requests made to Whiteboard. It means that anyone

can modify any whiteboard ID (wid).

In LAMS we introduce a hash of wid + accesstoken. Users do not know

access token, so they can not generate the hash for another wid.

The hash is simple Java hashCode() function, sufficient for this

situation.

The hash does not include author name as it is not present in many use

cases.

The hash optionally has a different form: source wid + wid +

accesstoken. It is when copyfromwid parameter is present. In this case

the target canvas is using standard wid and hash, but for the extra call

to source canvas we use source wid and the modified hash. This modified

hash is only usable to copy content from this particular source wid to

this particular target wid, so users can not use the hash to draw on the

source canvas.
