Tuple:frommap() or insert_map()

[sharonovd]

Please consider adding built-in tuple:frommap() functionality.
That would be useful for transparent managing formatted spaces via REST API

Possible examples (originally proposed by @Igorjan94):

tarantool> t = {subscriber_status_id = 42, subscriber_id = 1, phone = '79160000000', contract_id = 1}
---
...

tarantool> subscriber:fromMap(t)
---
- [1, 1, '79160000000', 42]
...

tarantool> subscriber:insert(t)
---
- [1, 1, '79160000000', 42]
...```

Regarding inserts - please also consider case when primary id is autogenerated (e g via sequence), and thus not provided by inserter

@TarantoolBot document
Title: document new space method in Lua: frommap()
Space:frommap() allows to generate a well-formatted tuple ready to insert into the space from a Lua dictionary with pairs field_name = field_value.
For example:

format = {}
format[1] = {name = 'field1', type = 'unsigned'}
format[2] = {name = 'field2', type = 'unsigned'}
s = box.schema.create_space('test', {format = format})
pk = s:create_index('pk')
t = s:frommap({field1 = 100, field2 = 200})
s:insert(t)

By default, it returns a tuple as cdata, but you can pass the option: frommap(tuple, {table = true}), and then the result will be a Lua tale.

@Gerold103: Accept.
