nice to have

Missing Feature

User john runs a terraform task that creates a VM and VM name should include name john-, we can use :

• Environment with variable called TF_VAR_semaphoreuser - var.semaphoreuser is accessible in terraform automatically - but environment does not belong to John it belongs to the project so this is not usable at scale
• Survey variable - every task need to have survey variable semaphoreuser asking user to fill its own username - there is nothing preventing to give any other value. Also it is tedious to ask semaphore user name at every task execution

Implementation

• ability for environment and have value set by UI
• example environment I need the value is username from GET /api/user

If the value of the variable is not resolved when running a task then - the variable should not exist at all (default empty value is not wanted - task failure is expected if variable does not resolve to username)
