rpc, evm: use binary search to estimate gas (#272)

* do binary search to estimate gas

Closes #268

- Also refactor ApplyMessage to be more reuseable

move binary search to rpc api side to have a clean context each try

remove EstimateGas grpc api

* extract BinSearch function and add unit test

* do estimateGas in grpc query

description: >-
A URL/resource name that uniquely identifies the type of
the serialized
protocol buffer message. This string must contain at
least
one "/" character. The last segment of the URL's path
must represent
the fully qualified name of the type (as in
`path/google.protobuf.Duration`). The name should be in
a canonical form
(e.g., leading "." is not accepted).
In practice, teams usually precompile into the binary
all types that they
expect it to use in the context of Any. However, for
URLs which use the
scheme `http`, `https`, or no scheme, one can optionally
set up a type
server that maps type URLs to message definitions as
follows:
* If no scheme is provided, `https` is assumed.
* An HTTP GET on the URL must yield a
[google.protobuf.Type][]
value in binary format, or produce an error.
* Applications are allowed to cache lookup results based
on the
URL, or have them precompiled into a binary to avoid any
lookup. Therefore, binary compatibility needs to be preserved
on changes to types. (Use versioned type names to manage
breaking changes.)
Note: this functionality is not currently available in
the official
protobuf release, and it is not used for type URLs
beginning with
type.googleapis.com.
Schemes other than `http`, `https` (or the empty scheme)
might be
used with implementation specific semantics.

description: >-
`Any` contains an arbitrary serialized protocol buffer
message along with a
URL that describes the type of the serialized message.
Protobuf library provides support to pack/unpack Any values
in the form
of utility functions or additional generated methods of the
Any type.
Example 1: Pack and unpack a message in C++.
Foo foo = ...;
Any any;
any.PackFrom(foo);
...
if (any.UnpackTo(&foo)) {
...
}
Example 2: Pack and unpack a message in Java.
Foo foo = ...;
Any any = Any.pack(foo);
...
if (any.is(Foo.class)) {
foo = any.unpack(Foo.class);
}
Example 3: Pack and unpack a message in Python.
foo = Foo(...)
any = Any()
any.Pack(foo)
...
if any.Is(Foo.DESCRIPTOR):
any.Unpack(foo)
...
Example 4: Pack and unpack a message in Go
foo := &pb.Foo{...}
any, err := ptypes.MarshalAny(foo)
...
foo := &pb.Foo{}
if err := ptypes.UnmarshalAny(any, foo); err != nil {
...
}
The pack methods provided by protobuf library will by
default use
'type.googleapis.com/full.type.name' as the type URL and the
unpack
methods only use the fully qualified type name after the
last '/'
in the type URL, for example "foo.bar.com/x/y.z" will yield
type
name "y.z".
JSON
====
The JSON representation of an `Any` value uses the regular
representation of the deserialized, embedded message, with
an
additional field `@type` which contains the type URL.
Example:
package google.profile;
message Person {
string first_name = 1;
string last_name = 2;
}
{
"@type": "type.googleapis.com/google.profile.Person",
"firstName": <string>,
"lastName": <string>
}
If the embedded message type is well-known and has a custom
JSON
representation, that representation will be embedded adding
a field
`value` which holds the custom JSON in addition to the
`@type`
field. Example (for message [google.protobuf.Duration][]):
{
"@type": "type.googleapis.com/google.protobuf.Duration",
"value": "1.212s"
}
