Cache Vault secrets using the plugin

[vinamrahw]

What feature do you want to see added?

Currently there is no caching of vault secrets in jenkins plugin which is causing thousands of read requests to Vault for the same secret. Caching will heavily reduce the read requests from jenkins to Vault

never cache a secret .......

In my Jenkins instance i have around 100 requests per second to vault.
It has a large number of jobs that work against a subversion server, and is probably due to each job pulling for repo changes.
So I would also need some form of caching, I know one should not cache secretes but this becomes insane without it.
